摘要
介绍了一种高性能的电站直流屏电源系统,采用了新颖的双管双正激高频开关电路,输出功率为7kW;PWM波形由SG2846产生,W78E52作为主控芯片,提供了485/232两种总线通讯方式。实验证明,该电源体积小,性能满足要求。
This paper presents a high quality power supply for substation DC panel, which uses high frequency switch circuit with a novel two-transistor two-forward converters. The output power is 7kW, the SG2846 produces PWM pulse, the main control unit using W78E52 affords two communication mode 485/232. The experiment proves this power supply has small cubage, and its performance meets the demand.This work is supported by Science and Research Fund of Education Department of Shandong Province(No.J98B03).
