Problems solved by technology

[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 function of voltage stabilization. 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.
