| Abstract: | In allusion to the problems in the operation of the DC power supply systems of the first-stage and second-stage pro＂ jects at Huaibei Power Plant, which have existed for a long time. This paper analyzes the necessity of transform for the DC power supply systems, elaborates the performance characteristics of the high frequency switching power supply, working principle of the high frequency switching power supply module and PWM power frequency conversion technology with the introduction of the typical transform scheme for the original DC power supplies by using the high frequency switching power supply at Huaibei Power Plant. |
