摘要：
High-voltage pulse power supply is an important means of producing low-temperature plasma, which is widely used in the field of discharge plasma. Aiming at the continuous improvement of electromagnetic launch technology on the power density of high-voltage power supply, a miniaturization and cascade high-voltage pulse power supply is designed. The technical specifications of the power supply are: pulse voltage 0~20 kV, pulse width 5~30 μs and repetition frequency 0~10 kHz( adjustable). The cascaded voltage superposition mode is used to divide the power supply into 40 repetitive cell modules with each 500 V. The semiconductor switch insulated gate bipolar transistor (IGBT) is controlled by the optical fiber trigger system to obtain the high-voltage pulse waveform with different pulse widths and repetition frequencies. The design advantage lies in the modularization of high voltage power supply for low voltage. The main circuit and switch driver circuit of each stage are integrated on a PCB board, which greatly simplifies the system structure and reduces the system volume. The pulsed power supply is tested under resistive and electrode load, which show that the consistency of the optical fiber trigger system is good, and the output index meets the design requirements. © 2019, High Voltage Engineering Editorial Department of CEPRI.
