| Abstract: | This paper puts forward an new high frequency switching power supply module for direct current electric point machine. The module can produce high power and high voltage output through adopting two-transistor two-forward converter and power factor correction. In this article, its structure and principle is described in details. It is proved that the new power supply can absolutely replace the old one. |
