Abstract
A power converter, short circuit protection circuit, and control method are disclosed herein. The power converter is configured to generate an output voltage and includes a semiconductor switch, a short circuit protection circuit, and a signal processing module. The semiconductor switch is configured to adjust the output voltage according to a driving signal. The short circuit protection circuit is configured to generate a short circuit protecting signal according to a control signal and a short circuit status of the semiconductor switch. The signal processing module is configured to generate the control signal and the driving signal according to a modulating signal, and to turn off the semiconductor switch according to the short circuit protecting signal. A delay duration is present between the modulating signal and the control signal, and the semiconductor switch is turned on during the delay duration.
