POWER CONVERSION SYSTEM WITH ZERO-VOLTAGE START-UP MECHANISM, AND ZERO-VOLTAGE START-UP DEVICE

摘要

zero- voltage start-up mechanism and zero- power conversion system is disclosed having a voltage startup device. The system power converter circuit , the power factor correction unit , a storage capacitor , storage switching unit , and the zero- voltage detection module comprises : Save switching unit connected in series to the storage capacitor , zero - voltage is controlled by the detection module . Zero - voltage detection module detects the timing of the input voltage is low level , and outputs a control signal to turn on a storage switching . Therefore, the present invention ensures that the input voltage is low level when the electric power conversion system is turned on in order to protect it from current surges the system . ;
