Description

technical field [0001] The present invention relates to the technical field of power conversion, and more particularly, to a power circuit. Background technique [0002] With the rapid development and wide application of active solid-state phased array technology, it has become a very urgent need to develop high-power, small-volume, and low-ripple power modules for active solid-state phased array radar systems. Moreover, the power supply mode of high-voltage direct current and low-voltage high-current output poses a severe challenge to the performance of the power module. For radars of different bands, the higher the radar band, the stricter the requirements for the front power supply volume. Sometimes the height of the power supply is below 8mm. The high power density of the power supply module has become an important issue to be solved in the development of the power supply module. For traditional DC / DC power modules, it is difficult to design transformers when high volta...
