In the field of pulsed plasma discharge, the utilization of LC charging and discharging circuits is a conventional method for achieving plasma breakdown. However, conventional LC charging and discharging power supplies can only achieve unidirectional current. In order to meet the requirements of bidirectional current operation for relevant tokamak devices, this paper proposes the design of a pulsed power supply circuit based on an H-bridge structure. Moreover, key components such as semiconductor switches and pulse capacitors in the circuit are carefully selected. By conducting simulation calculations on the main circuit of the power supply and determining the control timing of the H-bridge switches, followed by experimental validation, the newly designed H-bridge topology pulsed power supply meets the design requirements.

摘要

In the field of pulsed plasma discharge, the utilization of LC charging and discharging circuits is a conventional method for achieving plasma breakdown. However, conventional LC charging and discharging power supplies can only achieve unidirectional current. In order to meet the requirements of bidirectional current operation for relevant tokamak devices, this paper proposes the design of a pulsed power supply circuit based on an H-bridge structure. Moreover, key components such as semiconductor switches and pulse capacitors in the circuit are carefully selected. By conducting simulation calculations on the main circuit of the power supply and determining the control timing of the H-bridge switches, followed by experimental validation, the newly designed H-bridge topology pulsed power supply meets the design requirements.
