  • POWER CONVERTER WITH PROTECTION MECHANISM FOR DIODE IN OPEN-CIRCUIT CONDITION AND PULSE-WIDTH-MODULATION CONTROLLER THEREOF
    Publication number: 20110133714
    Abstract: A power converter with a protection mechanism for a diode in an open-circuit condition includes a DC to Dc (DC/DC) conversion circuit, a detection and protection circuit, a pulse-width-modulation (PWM) signal generator, and a logic gate. The detection and protection circuit is used for detecting an open-circuit condition of the diode of the DC/DC conversion circuit. The logic gate receives an output signal of the detection and protection circuit and a PWM signal outputted by the PWM signal generator. When the diode is in an open-circuit condition, the PWM signal cannot be transmitted to a power switch of the DC/DC conversion circuit due to the output signal of the detection and protection circuit.
