  • DRIVING CIRCUIT, POWER CONVERSION DEVICE AND DRIVING METHOD OF POWER SWITCH
    Publication number: 20190074760
    Abstract: A driving circuit includes a power switch driver and a plurality of current-limiting circuits. The power switch driver is configured to output a driving signal according to a switching signal. Each of the current-limiting circuits has an input terminal electrically coupled to a corresponding one of output terminals of the power switch driver respectively. Output terminals of the current-limiting circuits are electrically coupled to a control terminal of a power switch. The power switch driver is configured to selectively output the driving signal to one of a plurality of output terminals according to a load state of the power switch, such that the driving signal is outputted to the control terminal of the power switch via one of the current-limiting circuits.
