Abstract

Abstract

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
- semiconductor laser,
- pulsed current source,
- cascade superposition,
- linear regulator,
- closed-loop control
