It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.
[0048] See also Figure 1 , Figure 1 A schematic diagram of an isolation driving device with an error reporting function according to an embodiment of the present disclosure is shown.
[0049] The isolation driving device is used to control the gate voltage of the transistor to be driven. Figure 1 As shown, the device comprises:
[0050] A single channel isolation component 30 is disposed between the input side 10 and the output side 20;
[0051] The input side 10 and the output side 20 periodically perform signal transmission operations, wherein:
[0052] In the first time period of each cycle, the input side 10 sends a control signal to the output side 20 through the single-channel isolation component 30, and the control signal is used to control the voltage of the gate of the transistor to be driven;
[0053] In the second time period of each cycle, the output side 20 sends a handshake signal to the input side 10 through the single-channel isolation component 30 when receiving the control signal;
[0054] Among them, if the input side 10 receives the handshake signal or does not receive the handshake signal for a cumulative number of times less than K times, the signal transmission operation of the next cycle is started; if the input side 10 does not receive the handshake signal for K consecutive times, an error report signal is sent and the signal transmission operation is stopped, and K is a positive integer.
[0055] In the embodiment of the present disclosure, in the first time period of each cycle, the input side 10 sends a control signal to the output side 20 through the single-channel isolation component 30. In the second time period of each cycle, when the output side 20 receives the control signal, it sends a handshake signal to the input side 10 through the single-channel isolation component 30. If the cumulative number of times that the input side 10 receives the handshake signal or does not receive the handshake signal is less than K times, the signal transmission operation of the next cycle is started; if the input side 10 does not receive the handshake signal for K consecutive times, an error reporting signal is sent and the signal transmission operation is stopped. In this way, the control signal and fault signal transmission are realized through the single-channel isolation component 30, the cost is reduced, and the safety and reliability are relatively high.
[0056] The embodiments of the present disclosure do not limit the specific form, generation method, and specific error type of the error reporting signal. Those skilled in the art can set it according to actual conditions and needs, and implement it using relevant technologies. For example, the error reporting type may include undervoltage (UV), short circuit / saturation (SC / Saturation), overtemperature (OT), overvoltage (OV), etc. Of course, the isolation drive device can be configured with a corresponding fault detection circuit, such as an undervoltage detection circuit, a short circuit / saturation detection circuit, a temperature detection circuit, an overvoltage detection circuit, etc. The embodiments of the present disclosure do not limit the specific implementation method of the fault detection circuit, and those skilled in the art can set it according to actual conditions and needs.
[0057] The disclosed embodiment does not limit the specific implementation method of the single-channel isolation component 30. Those skilled in the art may select a suitable isolation scheme to implement the single-channel isolation component 30 according to actual conditions and needs. For example, in one possible implementation, the single-channel isolation component 30 is used to achieve electrical isolation and signal transmission between the input side and the output side. The single-channel isolation component 30 may include an optocoupler isolator, a capacitor isolator, an electromagnetic isolator, etc.
[0058] It should be understood that the isolation driving device with error reporting function is a gate driver with a single-channel isolation component 30 (only one isolation channel). The embodiment of the present disclosure does not limit the specific implementation method in the gate driver. The isolation driving device with error reporting function can have various components of a common gate driver to achieve its gate driving function. For example, a gate driving module can also be included on the output side to generate a gate driving signal according to the control signal to achieve the driving of the transistor gate.
[0059] In a possible implementation, the device may also be connected to a controller (not shown), and the controller is used to output a control signal, wherein the control signal is a high level or a low level. The embodiment of the present disclosure does not limit the specific implementation of the controller, and those skilled in the art may set it according to actual conditions and needs. In one example, the controller may include a processing component, and exemplary, the processing component includes but is not limited to a separate processor, or a discrete component, or a combination of a processor and a discrete component. The processor may include a controller having an execution instruction function in an electronic device, and the processor may be implemented in any appropriate manner, for example, by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components. Inside the processor, the executable instructions may be executed by hardware circuits such as logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers.
[0060] In a possible implementation, the input side 10 and the output side 20 may include multiple ports for signal transmission. The disclosed embodiment does not limit the specific number of ports of the input side 10 and the output side 20. For example, the port of the input side 10 includes at least one error reporting port 110 and one signal input port 120, and the port of the output side 20 includes at least one power port 210 and one signal output port 220. The port of the output side 20 may also include a detection port 230. Of course, the number of the error reporting port 110, the signal input port 120, the power port 210, the signal output port 220, and the detection port 230 may be configured according to actual conditions and needs. In addition, other ports may also be included as long as they match the number of pins of the existing package.
[0061] See also Figure 2 , Figure 2 A schematic diagram of an isolation driving device with an error reporting function according to an embodiment of the present disclosure is shown.
[0062] In one example, if Figure 2 As shown, the input side 10 of the isolation driving device may include, for example, a signal input port 120 and an error reporting port 110, and both the signal input port 120 and the error reporting port 110 are connected to the controller.
[0063] The signal input port 120 is used to receive the control signal from the controller, and the error reporting port 110 is used to send the error reporting signal to the controller.
[0064] In a possible implementation, the output side 20 is provided with a filter circuit (not shown) for filtering the control signal received through the single-channel isolation component 30 to filter out burr signals in the control signal. The embodiments of the present disclosure do not limit the specific implementation of the filter circuit, and those skilled in the art can set it according to actual conditions and needs.
[0065] In a possible implementation manner, the output side 20 sends the handshake signal when the duration of receiving the control signal reaches a first preset duration.
[0066] Since the filtering operation of the filtering circuit on the control signal takes a certain amount of time, the output side 20 needs to determine that the control signal is stably received when the duration of receiving the control signal reaches a first preset duration, and then send the handshake signal to the input side 10.
[0067] Of course, the first preset duration may be a period before the second time period. For example, the timing may be started from when the control signal is first received. When the timing reaches the first preset duration, the output side 20 starts to send the handshake signal.
[0068] See also Figure 3 , Figure 3 A schematic diagram of an input side circuit in an isolation driving device with an error reporting function according to an embodiment of the present disclosure is shown.
[0069] In a possible implementation, Figure 3 As shown, the input side is also connected to an input side circuit, and the input side circuit includes:
[0070] A first input resistor Ri1, a second input resistor Ri2, and a first transistor Q1, wherein:
[0071] The first end of the first input resistor Ri1 and the first end of the second input resistor Ri2 are used to receive a power supply voltage VCC.
[0072] The second end of the first input resistor Ri1 is connected to the collector of the first transistor Q1 and the signal input port 120, and is used to output a control signal (high level or low level).
[0073] The second end of the second input resistor Ri2 is connected to the error reporting port 110.
[0074] The base of the first transistor Q1 is used to receive an input signal (a control signal sent by a controller), and the emitter of the first transistor Q1 is grounded.
[0075] Exemplarily, the input is a conduction control signal of the first transistor Q1.
[0076] For example, Figure 3 As shown, if the first transistor Q1 is turned on, the level of the signal input port 120 is pulled low, and no current flows into the signal input port 120. In this case, the output side 20 (signal output port 220) is logic low. If the first transistor Q1 is turned off, the level of the signal input port 120 is pulled high, and current flows into the signal input port 120 and is transmitted to the output side 20 through the isolation component 30 (such as an optical coupler isolator). In this case, the output side 20 (signal output port 220) is logic high.
[0077] For example, Figure 3 As shown, the error reporting port 110 is an open drain output connected to a pull-up resistor. The error reporting port 110 in normal operation is high impedance, that is, the error reporting port 110 is at a high level; when an error occurs, the error reporting port 110 is pulled low. Of course, the error reporting port 110 can also be designed as a normal logic output signal, which is not limited in the embodiment of the present disclosure.
[0078] In a possible implementation, the output side 20 further includes a power port 210 , and the power port 210 includes a first power port and a second power port, wherein the first power port is used to receive a power supply voltage, and the second power port is grounded.
[0079] See also Figure 4 , Figure 4 A schematic diagram of an output side circuit in an isolation driving device with an error reporting function according to an embodiment of the present disclosure is shown.
[0080] For example, Figure 4 As shown, the output side is also connected to an output side circuit, and the output side circuit includes:
[0081] The first output capacitor CN, the first output resistor Ro1, the second output resistor Ro2 and the first output diode D1, wherein:
[0082] The first end of the first output capacitor CN is connected to the signal output port 220.
[0083] The second end of the first output capacitor CN is connected to the cathode of the first output diode D1 and the first end of the first output resistor Ro1.
[0084] The anode of the first output diode D1 is connected to the first end of the second output resistor Ro2.
[0085] The second end of the first output resistor Ro1 and the second end of the second output resistor Ro2 are connected to the gate of the transistor Q to be driven.
[0086] For example, Figure 4 As shown, the second power terminal 211 may also be connected to the source of the transistor Q to be driven.
[0087] For example, Figure 4 As shown, the output side circuit may further include a first detection capacitor Cblk, a first detection resistor Ro3, and a first detection diode D2, wherein:
[0088] The detection terminal 230 is connected to a first end of the first detection capacitor Cblk and a first end of the first detection resistor Ro3, and a second end of the first detection capacitor Cblk is grounded.
[0089] The second end of the first detection resistor Ro3 is connected to the anode of the first detection diode D2.
[0090] The cathode of the first detection diode D2 is connected to the drain of the transistor Q to be driven.
[0091] Wherein, when the level of the detection port 230 changes compared with the preset level, the output side 20 does not send the handshake signal.
[0092] In a possible implementation manner, the length of the first time period is 200 to 600 ns, the length of the second time period is 200 to 300 ns, and the first preset time length is 100 to 150 ns.
[0093] Exemplarily, the first time period is 500 ns in length, for example. The input side 10 sends a control signal within 500 ns, stops sending the control signal after 500 ns, and waits for a handshake signal returned by the output side 20 .
[0094] Exemplarily, the first preset time length is, for example, 120ns, and the second time period is, for example, 190ns, wherein, after the output side 20 receives the control signal for a time length of 120ns, the isolation channel switches from the receiving state to the sending state, and starts to send a handshake signal to the input side 10 through the isolation channel within 30ns, and the handshake signal lasts, for example, 40ns, after which the isolation channel switches back to the receiving state. It should be understood that the state switching mode of the isolation channel (single-channel isolation component 30) is not limited in the embodiment of the present disclosure, and those skilled in the art can use relevant technologies to achieve control according to actual conditions and needs, and the states of the two sides of the isolation channel are relative, for example, when the input side 10 sends a control signal, the isolation channel is configured to be in a sending state of sending a signal from the input side 10 to the output side 20, and relatively speaking, from the output side 20, the isolation channel is configured to be in a receiving state.
[0095] Exemplarily, if the input side 10 receives a handshake signal or does not receive the handshake signal for a cumulative number of times less than K times, it is considered that no fault has occurred, and the control signal continues to be sent after the handshake signal stops.
[0096] Exemplarily, if the input side 10 does not receive the handshake signal for K consecutive times, it is considered that a fault has occurred, and an error reporting signal can be sent and the signal transmission operation can be stopped, wherein the method of sending the error reporting signal includes but is not limited to lowering the level of the error reporting port 110 (the error reporting signal is, for example, a low level), and reporting the error reporting signal to the controller.
[0097] The disclosed embodiment can improve anti-interference performance by requiring several consecutive absences of handshake signals to trigger a fault alarm.
[0098] According to one aspect of the present disclosure, an electronic device is provided, and the electronic device includes the isolation driving device with error reporting function.
[0099] In a possible implementation, the electronic device includes a power supply device and an electric drive device. The embodiments of the present disclosure do not limit the specific types of the power supply device and the electric drive device. Those skilled in the art can set them according to actual conditions and needs. For example, the power supply device and the electric drive device may include a vehicle charger, an inverter, an uninterruptible power supply UPS, AC / DC and DC / DC converters, etc.
[0100] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
