Embodiment Construction
[0039] Such as figure 1 As shown, the high-power high-frequency switching power supply in one embodiment of the present invention is composed of two parts as a whole, one part is a three-phase voltage type PWM rectifier, which converts three-phase alternating current into direct current; the other part is composed of a single-phase full-bridge inverter, A high-frequency DC / DC converter composed of a high-frequency coupling transformer and a low-voltage rectifier converts direct current into high-frequency alternating current through a single-phase inverter, and then transmits energy to the low-voltage side through a high-frequency coupling transformer, and then converts high-frequency power through a low-voltage rectifier. The high-frequency AC power supply is converted into DC power, and after passing through the filter circuit, a stable DC voltage and current is output to realize efficient energy transmission.
[0040] The method of the present invention is also composed of...
