Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a low-loss power electronic transformer. Background technique [0002] In the prior art, the main function of the transformer is voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc., but the output of the current low-voltage transformer is not stable enough, especially for precision electronic equipment, which requires a stable output voltage. If the existing coil transformer is used, there is no voltage stabilizing function. Therefore, it is necessary to improve the voltage stabilization of the coil transformer. In addition, the loss of the power transformer in the prior art is high, which is not conducive to energy saving. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a low-loss power electronic transformer in order to solve the above problem...
