Description

Technical Field

[0001] The present invention relates to the technical field of DC voltage doubling, and particularly relates to a boost energy storage discharge device and system. Background Art

[0002] At present, in an electronic circuit, when the voltage required by the subsequent stage is an integer multiple higher than that of the previous stage and the required current is not much, a voltage doubling circuit is needed. It is composed of a diode with a relatively high reverse peak voltage and a capacitor with a relatively high withstand voltage. Voltage doubling rectification can boost a relatively low AC voltage through a rectifier diode and a capacitor with a relatively high withstand voltage, so as to output a relatively high DC voltage. The voltage doubling rectification circuit is generally divided into a two - fold voltage, three - fold voltage, and multi - fold voltage rectification circuit according to how many times the output voltage is of the input voltage, and it is commonly used in an environment of low current and high voltage and cannot be used in an environment of large current and high voltage.

However, the existing voltage doubling rectification circuit outputs a doubled voltage continuously when powered on, and a load needs to be added at the output end to discharge to prevent over - voltage.

The second end of the capacitor C4 is connected to the positive electrode of the diode D3. The negative electrode of the diode D3 is also connected to the positive electrode of the diode D4. The negative electrode of the diode D4 is connected to the energy storage unit. The voltage multiplier circuit is a multi-stage voltage multiplier circuit. By utilizing the guiding effect of the diode, the capacitor is charged and discharged, and the voltages of multiple capacitors are superimposed on each other, so that a higher voltage output can be obtained. The DC voltage Vout1 is input to the first end of the capacitor C2, and after the voltages of multiple capacitors are superimposed and boosted to obtain Vout2, it is output to the energy storage unit.

[0045] As an optional implementation manner, in an invention implementation, refer to Figure 4 As shown, the energy storage unit includes: a discharge resistor R4, a diode D5, an energy storage capacitor C6, a diode D6, a thyristor Q2, and a resistor R5. The first end of the discharge resistor R4 is connected to the negative electrode of the diode D4.

The energy storage capacitor C6 is used for storing the voltage Vout2 boosted by the voltage multiplier unit. The diodes D5 and D6 are used to prevent high reverse voltage to protect the energy storage unit. The gate of the thyristor Q2 is used to receive the trigger signal DRV4 of the trigger unit and conduct after the trigger unit issues a high-level trigger signal DRV4, so that the voltage Vout2 in the energy storage capacitor C6 is output to the load through the Vout2+ terminal. When the trigger unit does not issue a high-level trigger signal DRV4, the thyristor Q2 is cut off, and the voltage Vout2 in the energy storage capacitor C6 is not output. The resistor R5 is a pull-down resistor grounded, which is used to maintain the steady state of the thyristor Q2 and improve the circuit stability.

[0046] As an alternative embodiment, in one implementation of the invention, refer to Figure 5 As shown, the detection unit includes: a resistor R6, a resistor R7, and a chip U1 connected in sequence. The first end of the resistor R6 is connected to the second end of the discharge resistor R4. The first end of the resistor R7 is connected to the second end of the resistor R6 and the second pin of the chip U1. The second end of the resistor R7 is grounded. The sixth pin of the chip U1 is connected to the first end of the resistor R1. The resistor R6 and the resistor R7 are sampling resistors for collecting the voltage Vout2 in the energy storage capacitor C6 and outputting it to the second pin of the chip U1. The chip U1 compares the collected voltage Vout2 with a preset voltage value, and when the voltage Vout2 is less than the preset voltage value, it outputs a high-level signal DRV3 to the first end of the resistor R1, i.e., the gate of the transistor Q1, to control the transistor Q1 to conduct. Then, the DC voltage Vout1 is boosted by the voltage multiplier circuit to obtain Vout2. When the voltage Vout2 is not less than the preset voltage value, the chip U1 outputs a low-level signal DRV3 to the first end of the resistor R1, i.e., the gate of the transistor Q1, to control the transistor Q1 to turn off. Then, the voltage multiplier circuit stops boosting, and the voltage Vout2 that has been boosted to the preset value is stored in the energy storage capacitor C6 and waits to output the voltage after the trigger unit outputs a trigger signal.

[0047] As an alternative embodiment, in one implementation of the invention, refer to Figure 1 As shown, the trigger unit includes: an optical signal detection circuit and a trigger output circuit. The optical signal detection circuit is used to receive an optical signal and convert it into a voltage signal. The trigger output circuit is connected to the optical signal detection circuit and is used to trigger the energy storage unit to output a voltage according to the voltage signal of the optical signal detection circuit. The optical signal detection circuit converts an external optical signal into an electrical signal and outputs it to the trigger output circuit, and the trigger output circuit then controls the energy storage unit to discharge and output a preset voltage according to the voltage signal of the optical signal detection circuit.

[0048] As an alternative embodiment, in one implementation of the invention, refer to Figure 5 and Figure 6As shown in the figure, the boost energy storage and discharge device further includes: a signal latch. The input end of the signal latch is connected to the optical signal detection circuit and the detection unit, and the output end of the signal latch is connected to the trigger output circuit. It is used to receive the optical signal once and send a trigger signal to the trigger output circuit. When the optical signal detection circuit detects an external optical signal and sends a high-level voltage signal Vout4 to the first input end of the signal latch, and when the sampling resistor R6 and the resistor R7 of the detection unit collect a voltage Vout2 not less than the preset voltage value and output a high-level voltage signal Vout3 to the second input end of the signal latch, only after performing an AND logic operation on the high-level voltage signal Vout4 of the external optical signal and the high-level voltage signal Vout3 of the detection unit, will the signal latch output a high-level voltage signal Vout5 to the trigger output circuit. The trigger output circuit outputs a high-level trigger signal to control the voltage output. If the optical signal detection circuit does not detect an external optical signal or the boosted voltage Vout2 collected by the detection unit does not exceed the preset voltage value, the signal latch will not output a high-level voltage signal Vout5, that is, the trigger output circuit does not control the energy storage unit to output voltage. At the same time, the signal latch is also used to hold and store the state of the control signal. Once the signal latch receives the effective high-level voltage signal Vout3 of the detection unit, it will wait for the external optical signal Vout4 of the optical signal detection circuit and maintain the AND logic with this state until it receives another effective input signal to change the current state, and make the received external optical signal valid only once, keep locked before it is valid, and automatically reset after it is valid.

[0049] As an alternative implementation, in an invention implementation, refer to Figure 6 As shown in the figure, the optical signal detection circuit includes: a photoelectric converter U2, a resistor R8, and a capacitor C7.

The power supply end of the photoelectric converter U2 and the first end of the resistor R8 are both connected to an external 5V power supply, and the external 5V power supply supplies power to the photoelectric converter U2. The photoelectric converter U2 is used to convert the optical signal into an electrical signal and output a high-level voltage signal Vout4 to the first input end of the signal latch through the output end. The resistor R8 is a current-limiting resistor used to protect the photoelectric converter U2, and the capacitor C7 is a bypass capacitor used to improve the stability of the output of the photoelectric converter U2.

[0050] As an alternative implementation, in an invention implementation, refer toFigure 7 As shown, the trigger output circuit includes: a driving chip U3, a resistor R9, a resistor R10, and a capacitor C8.

The first end of the resistor R10 is also connected to the energy storage unit. The second end of the resistor R10 is connected to the fifth pin of the driving chip U3. When the high-level voltage signal Vout4 of the optical signal detection circuit and the high-level voltage signal Vout3 of the detection unit perform an AND logic operation, the signal latch outputs a high-level voltage signal Vout5 to the second pin and the fourth pin of the driving chip U3. After receiving the high-level voltage signal Vout5, the driving chip U3 outputs a high-level trigger signal DRV4 through the first end of the resistor R10. The high-level trigger signal DRV4 is output to the gate of the thyristor Q2 of the energy storage unit to turn on the thyristor Q2.
