As solid state lasers for ranging and illumination demand higher performance in terms of miniaturization and efficiency from their driving sources,the traditional method of using MOSFETs in the linear region to control pulse current suffers from excessive thermal losses,resulting in low efficiency for low voltage,high current pulse power supplies.In this paper,an innovatively designed intelligent control method for the MOSFET gate drive voltage is implemented,utilizing an FPGA (Field Programmable Gate Array) to achieve dynamic algorithm adjustments.Combining with a dual closed loop control architecture (current closed loop control and Cuk circuit based voltage closed loop control),the method overcomes the bottleneck of low efficiency in traditional power supplies,achieving fast rise time,no overshoot,and high efficiency in pulse power delivery.Experimental results show that at a 15 A pulse output,the overshoot rate is less than 2%,the rise time is reduced to 9.92 μs,and the power efficiency reaches 90.94%.The system leverages FPGA programmability to achieve adjustable pulse currents from 10 A to 50 A (with 1 A steps),adjustable repetition rates from 1Hz to 100 Hz,and adjustable pulse widths from 150 μs to 400 μs,compatible with laser loads of 8～20 V.By replacing analog linear regulation with digital control,the contradiction between dynamic response and precision control is resolved.This study provides a new solution for high efficiency and miniaturized high precision pulse power supplies.
