Abstract:
A pre-charge control circuit includes a control unit, a conversion unit, and a pre-charge switch. The control unit provides a control signal according to a PWM signal, and the conversion unit provides a control voltage according to the control signal. The pre-charge switch adjusts a magnitude of the current flowing through the input path of the electronic circuit according to the control voltage.
