A rising edge and a falling edge of a PWM signal are captured and then an edge pulse signal is formed, the edge pulse signal is input to a primary side of a transformer, an output pulse is shaped at a secondary side of the transformer and finally recovered to be a PWM drive waveform with positive and negative voltage output, and then an MOSFET can be driven. Signals and energy are instantly transmitted at the edge of PWM, so the MOSFET isolation drive circuit is wide in isolation output wide duty ratio, which can reach 0-99.5%. A primary side pulse generation mode is different from a conventional capacitor-transformer combination driving mode, so a self-excitation frequency problem does not exist. If an input duty ratio abruptly changes, the output can follow with the change. No low-level gain phenomenon will occur, and a switch tube will not be connected for short time and burn out.
