Abstract

Abstract

With the progress of semiconductor manufacturing technology and the expansion of semiconductor laser applications, the demand of semiconductor laser for high power and miniaturized driving power becomes more and more urgent. It drives power supply towards the direction of higher power density and modular. This paper introduces the design of an all-brick drive power module based on BUCK circuit. The overall size of the power module is 116.8 mm×61 mm×12.7 mm, and the maximum output current is 12 A, the maximum adaptive output voltage is 50 V. The current ripple is less than 35 mA and the current stability reaches 0.67‰. At the same time, the power module is designed with overvoltage comparator and overcurrent protection circuit to ensure the reliability and the safe operation of laser load. The all-brick drive power module has been applied successfully in a project.
