介绍了一种大功率、宽输出电压范围的半导体激光器脉冲驱动电源的设计方法。根据半导体激光器脉冲驱动电源高电压、大电流的工作特性需求，脉冲放电环节采用多模块级联与功率开关管线性控制脉冲放电相结合的拓扑结构，这样既实现了脉冲电流平滑稳定，又提高了输出电压等级与功率。充电环节采取LCC谐振变换器结构，其抗负载短路和开路的能力非常适用于脉冲放电场合。该脉冲电源输出参数为：电压0~1000 V，电流1~160 A，脉宽200~250 μs，频率100 Hz内可调，具备较宽泛灵活的输出范围，可适应不同规模的激光二极管阵列。最后，分别通过单模块、两模块与三模块小功率级联型驱动实验验证了采用多模块级联与功率开关管线性控制脉冲放电相结合方法的可行性。

This paper introduces a new design method of wide range output voltage of semiconductor laser driver. According to the requirements of semiconductor laser driver, pulse discharge circuit is based on the multi-module cascade controlled linearly by a high IGBT. On this basis, it can achieve the pulse current smooth top and expand the output voltage range. The LCC resonant converter topology is used in the charging segment, and its capability of anti-load short circuit and open circuit are very applicable to pulse discharge. The pulse driver has a broad and flexible output voltage range which can adapt to semiconductor laser arrays of different size, and the pulse power output parameters are maximum output 1000 V/160 A, adjustable pulse width 200-250 μs and adjustable repetition frequency 100 Hz. Two modules and three modules low-power experiments were conducted to validate the proposed scheme, the experimental results demonstrate the feasibility of the method combining multi-module cascade and linear control pulse discharge
