  • Patent number: 8400797
    Abstract: A power conversion system with zero-voltage start-up mechanism and a zero-voltage start-up device are disclosed. The system includes a power conversion circuit, a power factor correction unit, a storage capacitor, a storage switching unit, and a zero-voltage detection module. The storage switching unit is serially connected with the storage capacitor, and particularly controlled by the zero-voltage detection module. The zero-voltage detection module detects a timing as an input voltage is at low level, and then outputs a control signal to turn on the storage switching unit. Therefore, the present invention assures that the power conversion system is turned on when the input voltage is at the low level, in order to suppress the system from a surge current.

  • Patent number: 8228646
    Abstract: Apparatus and method for draining stored power are disclosed, which the apparatus and method are applied to an EMI filter circuit for draining power. When the power supply circuit is not working, the apparatus provides a bleeder resistor to drain the power stored in the capacitors of the EMI filter circuit. On the other hand, when the power supply circuit is working, the apparatus provides an open-circuit resistor which has extremely large electrical resistance in order to stop draining power. Thus, the apparatus for draining stored power will not cause extra power waste.
