Comprising a direct-current power supply, a first resonant inductor (L1), a second resonant inductor (L2), a first diode (D1), a second diode (D2), a third diode (D3), a fourth diode (D4), a fifth diode (D5), a sixth diode (D6), a seventh diode (D7), an eighth diode (D8), a first resonant capacitor (C1), a second resonant capacitor (C2), a first power switch tube (Q1), a second power switch tube (Q2) and a boosting transformer with a center tap. The drive circuit disclosed by the utility model not only can generate high-frequency bipolar pulse excitation waveforms on the excimer lamp, but also is suitable for various loads in different forms, such as an ozone generator and the like.

This application relates to the field of controlled nuclear fusion technology and provides a supercapacitor charging and discharging system, including: a supercapacitor module, an energy recovery system, a discharge system, a voltage detection circuit, and a voltage comparison circuit. The energy recovery system is connected to the supercapacitor module via a first control switch, and the discharge system is connected to the supercapacitor module via a second control switch. The input terminal of the voltage comparison circuit is connected to the first output terminal of the voltage detection circuit, and the output terminal of the voltage comparison circuit is connected to the control terminals of the first and second control switches respectively. The voltage comparison circuit outputs a first trigger signal when the output voltage of the voltage detection module is greater than a first reference voltage, and outputs a second trigger signal when the output voltage of the voltage detection module is less than the first reference voltage. The first trigger signal triggers the first control switch to close, and the second trigger signal triggers the second control switch to close. This achieves rapid discharge across the entire voltage range.
