摘要： There is provided an output voltage stabilizer for stabilizing an output voltage of a switching mode power supply by elimination power bounce appearing on the output voltage of the switching mode power supply. The output voltage stabilizer mainly includes a voltage comparator that compares a rectified DC voltage obtained by the rectification of an input AC voltage with a reference voltage and in response thereto generates an output signal, and a control switch that is biased according to the output signal of the voltage comparator and provides the power supply a drive signal to stabilize an output voltage of the power supply during the brownout or soft-start stage in the input AC voltage.
