[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The core of this application is to provide a hybrid current control method, device, electronic equipment and medium.

[0051] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] FIG1 is a flow chart of a hybrid current control method provided in an embodiment of the present application, as shown in FIG1 , comprising the following steps:

[0053] S10: Determine a target current value according to the AC voltage feedback value and the target voltage value.

[0054] S12: When the target current value is greater than the comparator current upper limit value and less than the target current upper limit value, based on the current loop control in the inverter, determine the original inductor current value corresponding to the current feedback value and the target current value.

[0055] S13: Clamp the original inductor current value according to the comparator current upper limit value to obtain a target inductor current value.

[0056] S14: Obtain a current peak value of a target inductor current value. If the current peak value is greater than a current upper limit value of the comparator, turn off pulse width modulation to reduce the target inductor current value.

[0057] In a specific embodiment, the hybrid current control method provided in the present application is applied to the inverter as shown in FIG. 2 , wherein the inverter includes a power supply Ve; capacitors C1 , C2 and C3; MOS tubes Q1 Q2 Q3 and Q4; inductors L1 and L2, and a switch S1 . The first end of the capacitor C3, the source of the MOS transistor Q1, and the source of the MOS transistor Q3 are all connected to the positive electrode of the power supply Ve; the second end of the capacitor C3, the drain of the MOS transistor Q2, and the drain of the MOS transistor Q4 are all connected to the negative electrode of the power supply Ve; the drain of the MOS transistor Q1 is connected to the source of the MOS transistor Q2 and the first end of the inductor L1; the drain of the MOS transistor Q3 is connected to the source of the MOS transistor Q4 and the first end of the inductor L2; the second end of the inductor L1 is connected to the first end of the capacitor C1 and the first end of the switch S1; the second end of the inductor L2 is connected to the second end of the capacitor C1 and the second end of the switch S1; the third end of the switch S1 is connected to the first end of the capacitor C2 and the first end of the motor load; the fourth end of the switch S1 is connected to the second end of the capacitor C2 and the second end of the motor load. The inverter principle under this structure is: generally, within one interruption cycle, several groups of drivers (MOS tubes Q1-Q4) will appear at the same time, and several groups of drivers will use the same set of pulse width modulation duty cycle, which will not be updated until the next interruption cycle. If the voltage across the inductor of the inverter (inductor L1 and L2) changes significantly at this time, the pulse width modulation cannot change in time, which may cause the power tube current to be too high and cause damage in severe cases.

[0058] Therefore, the present application proposes a hybrid current control method based on this structure, wherein, since the current inverter adopts dual closed-loop control of inductor current, the AC voltage feedback value and the target voltage value can be used as the input of the voltage loop based on the voltage loop control, so as to obtain the target current output by the voltage loop; wherein when the target current value is greater than the comparator current upper limit value and less than the target current upper limit value, it means that the target current value in the current circuit has exceeded the limit of the power tube, and it is necessary to perform inductor current lock peak control on it, that is, based on the current loop control in the inverter, determine the original inductor current value corresponding to the current feedback value and the target current value; then clamp the original inductor current value according to the comparator current upper limit value to obtain the target inductor current value, thereby protecting the power tube in the circuit through the target inductor current value determined after clamping at this time, and the target inductor current value at this time improves the off-grid load-carrying capacity of the inverter. After determining the current peak, it is also necessary to judge it. If the current peak at this time exceeds the comparator current upper limit, the power tube in the inverter will turn off the pulse width modulation to reduce the target inductor current value at this time. In order to avoid the target inductor current value determined after clamping being reduced too much, resulting in excessive ripple corresponding to the target inductor current, the pulse width modulation needs to be re-driven after a certain period of time to achieve the effect of increasing the switching frequency.

[0059] In addition, when the target current value is not greater than the comparator current upper limit value, it means that the target current value is also less than the target current upper limit value, which indirectly indicates that the current target current value does not exceed the current limit of the power tube in the circuit. At this time, the inductor current value determined according to the target current value and the current feedback value is the original inductor current value. At this time, there is no need to change the state of the pulse width modulation.

[0060] A hybrid current control method provided by the present application includes: determining a target current value according to an AC voltage feedback value and a target voltage value; when the target current value is greater than a comparator current upper limit value and less than a target current upper limit value, determining the original inductor current value corresponding to the current feedback value and the target current value based on the current loop control in the inverter; clamping the original inductor current value according to the comparator current upper limit value to obtain a target inductor current value; obtaining a current peak value of the target inductor current value, and if the current peak value is greater than the comparator current upper limit value, turning off pulse width modulation to reduce the target inductor current value. Among them, the present application reduces the inductor current by clamping the current peak value, and increases the switching frequency by turning off the pulse width modulation operation, thereby avoiding the problem that when the inductor current slope in the inverter changes suddenly, the main control chip cannot respond in time within the control interruption interval, thereby improving the safety of the inverter.

[0061] On the basis of the above embodiments, as a preferred embodiment, the specific steps for determining the target current value according to the AC voltage feedback value and the target voltage value are: obtaining the AC voltage feedback value; obtaining the target voltage value; and determining the target current value corresponding to the AC voltage feedback value and the target voltage value based on the voltage loop control in the inverter.

[0062] In a specific embodiment, the current inverter adopts the inductor current double closed-loop control, so the AC voltage feedback value v in the current inverter can be obtained first. fb and the target voltage value v target , and then the AC voltage feedback value v fb and the target voltage value v target As the input of the voltage loop control, the target current value i corresponding to the voltage loop control output is target ; For current loop control, the target current value i target As an input of the current loop control, it is also necessary to obtain the current feedback value i in the current inverter fb , so at this time the target current value i target and the current feedback value i fb As the input of the current loop control, the output inductor current value i 2 In this process, it may be necessary to adjust the inductor current value i 2 To perform clamping and other actions, it is also necessary to define the comparator current upper limit i peak1 and the target current upper limit value i peak2 , where the target current upper limit value i peak2 is in the current loop. When the target current value i target Not greater than the comparator current upper limit i peak1 When the target current i in the input of the current loop control is target The actual output inductor current value i 2 As shown in Figure 3. When the target current value i target Greater than the comparator current upper limit i peak1 and is less than the target current upper limit i peak2 When the target current i in the input of the current loop control is target is not affected, but the actual output inductor current value i 2 The upper limit value of the current of the comparator i peak1 Clamping, that is, obtaining the target inductor current value determined after clamping, as shown in Figures 4a and 4b. In Figure 4a, the target current value i target Compared with Figure 4b, it is larger, so the inductor current value i 2a Greater than i 2b , as shown in FIG4c, and the black area in FIG4c is i 2a Than i 2bIt can be seen that the hardware comparator limits the comparator current upper limit i peak1 Under the premise of increasing the target current value i target The limiting range can effectively increase the inverter load capacity.

[0063] On the basis of the above embodiment, as a preferred embodiment, after reducing the clamped inductor current value, a series of operations need to be performed on the pulse width modulation, which are specifically divided into two types. The first one is: obtaining the reduced target inductor current value in real time; if the reduced target inductor current value is not greater than the preset current threshold, starting the pulse width modulation to increase the current target inductor current value, and judging whether the increased target inductor current value is greater than the comparator current upper limit value; wherein the preset current threshold value is less than the comparator current upper limit value.

[0064] The second method is: obtaining a preset current threshold; obtaining a reduction speed for reducing the target inductor current value; determining a corresponding target time according to the preset current threshold and the reduction speed; judging whether the time for reducing the target inductor current value is not less than the target time; if the time for reducing the target inductor current value is not less than the target time, starting pulse width modulation to increase the current target inductor current value, and judging whether the increased target inductor current value is greater than the comparator current upper limit value; if the time for reducing the target inductor current value is less than the target time, maintaining the current pulse width modulation state.

[0065] In a specific embodiment, no matter which of the above methods is used, its function is to ensure that the inductor current value i 2 It will not be too low to cause excessive inductor current ripple. Therefore, when the inductor current value i 2 When the target inductor current value or the original inductor current value is reduced to the preset current threshold, the target inductor current value i 2 The process is achieved by turning off the pulse width modulation, so the pulse width modulation needs to be re-driven to increase the current inductor current value i 2 The control logic is shown in Figure 5, where if the pulse width modulation is not turned off, the real-time inductor current value i 1 The curve characterized by will continue to rise. When this solution is used to limit the inductor current, the inductor current value i 2 The curve characterized by the pulse width modulation is fluctuating within a certain range. The continuous driving and closing of the pulse width modulation increases the switching frequency and reduces the peak value of the inductor current as a whole, thereby protecting the power tube and other devices in the inverter. 1 is the target time, where ON represents the driving pulse width modulation, and OFF represents the turning off pulse width modulation.

[0066] Therefore, in summary, a hybrid current control method provided by the present application includes: determining a target current value according to an AC voltage feedback value and a target voltage value; when the target current value is greater than the comparator current upper limit value and less than the target current upper limit value, based on the current loop control in the inverter, determining the original inductor current value corresponding to the current feedback value and the target current value; clamping the original inductor current value according to the comparator current upper limit value to obtain the target inductor current value; obtaining the current peak value of the target inductor current value, if the current peak value is greater than the comparator current upper limit value, then turning off the pulse width modulation to reduce the target inductor current value. Among them, the present application reduces the inductor current by clamping the current peak value, and increases the switching frequency by turning off the pulse width modulation operation, thereby avoiding the problem that when the inductor current slope in the inverter suddenly changes, the main control chip cannot respond in time within the control interruption interval, thereby improving the safety of the inverter. At the same time, the present application also increases the limit range of the target current value, thereby effectively increasing the load capacity of the inverter.
