ADAPTIVELY CONTROLLED SOFT START-UP SCHEME FOR SWITCHING POWER CONVERTERS

摘要

switching power converter provides a voltage adjusted according to the desired control voltage to the load . Switching power converter comprises a switch controller for generating a control signal for controlling the switching transformer and connected to the switch . The switch controller monitors the sensed voltage representing an output voltage of the switching power converter . while the output voltage is shown is detected that the output voltage below the first threshold voltage , the switching power converter to operate in a current continuous mode, the switch controller to control the switching of the switch . During the sensed output voltage is above the first threshold voltage , the switching power converter to operate in a current discontinuous mode , the switch controller to control the switching of the switch . ;
