摘　　要：通过采用高压隔离变压器和大功率脉冲扼流圈等措施,解决了某大功率装置的大电流开关动作时,灯丝电源装置抗30 kV高压反馈脉冲的冲击问题,为大电流开关的灯丝加热提供了4路独立可调、高稳定度输出的电源。The filament supply device must bear 30 kV high voltage feedback pulse surged when the strong current switch is turned on, and it is burned easily. In this paper, a new design is introduced to deal with this problem. By using the high-voltage isolation transformer and high-powered pulse choke, this equipment could provide four separated, adjustable and high stable power supply for the heater filament.
