摘要：

针对托卡马克脉冲阶梯调制(Pulse step modulation,PSM)模块大功率IGBT驱动电路的要求,选取有源钳位反激变换器作为设计的主电路,详细介绍了电路主要元件设计方法,研究电路主开关管零电压开通和基于LM5025前馈控制的实现方案。并针对ITER射频波加热系统,设计了一款开关频率为480 kHz的驱动电源。试验结果表明,在允许的输入电压范围内实现了电路主开关管零电压开通和前馈控制,降低了开关损耗,提高了电路工作的可靠性。

关键词: 脉冲阶梯调制, 前馈控制, 零电压开通, 反激变换器, 有源钳位

Abstract:

Aiming at the requirements of high-power IGBT drive circuit of Tokamak’s pulse step modulation (PSM) module, an active clamp flyback converter is selected as the main circuit of the design, and the design method of the main components of the circuit is introduced in detail. Research on the zero-voltage turn-on of the main switch of the circuit and the implementation scheme based on the LM5025 feedforward control. For the ITER radio frequency heating system, a driving power supply with a switching frequency of 480 kHz is designed. The experimental results show that the zero-voltage turn-on and feedforward control of the main switch of the circuit are realized within the allowable input voltage range, which reduces the switching loss and improves the reliability of the circuit operation.

Key words: Pulse step modulation, feedforward control, zero voltage turn-on, flyback converter, active clamp
