The invention relates to an electronic device for voltage conversion, which uses a second controller to instantaneously sense an output voltage or an output current of a secondary side of a transformer used as a power switch, and generates a transient response control signal, and utilizes a coupling element. The control signal generated by the second controller is transmitted to the first controller on the primary side, and the first pulse signal for power switching is generated by the first controller to control the disconnection or conduction of the primary side winding. |
