摘要： A burst mode resonant power converter with high conversion efficiency has a rectifier, a power factor correction circuit, a resonant circuit, a controller, and a burst mode triggering unit. The maximum frequency switching end of the controller is connected to a maximum frequency variable circuit. When the load is medium or heavy, the maximum frequency variable circuit increases the maximum switch frequency of the controller. When the load is in the no-load or the light conditions, it reduces the maximum switch frequency thereof. Therefore, the controller reduces the number of times that the resonant circuit switches the bridge switch circuit. The conduction cycle of the 50% pulse signal output to the bridge switch circuit becomes longer. Larger energy can be transmitted at a time to the secondary coil of the transformer. This increases the overall efficiency.

摘要： A connection-sensing DC plug has an insulative body, a connection portion, two power terminals, a conductive sheet and a retractable pin. The connecting portion is adapted to electronically connect to a target device and has an isolation layer and a ground layer. The conductive sheet is mounted in the insulative body and contacts either the isolation layer or the ground layer. The retractable pin is movably mounted in the insulative housing parallel to the connecting portion, with one end securely engaging the conductive sheet and the other end protruding from the insulative body. When the DC plug is connected to the target device, the retractable pin is pressed and moves inward to bend the conductive sheet, turning the conductive sheet to a floating state and resulting in a trigger signal.

The hold-up time extension controlling device has a switch and an auxiliary capacitor. When an AC power source is normal, the switch is controlled to turn on according to the power factor correction circuit to make the auxiliary capacitor connecting to the storage capacitor in parallel to averagely have a ripple current. When the AC power source is interrupted, the switch is controlled to turn off. At the time, the hold-up time extension circuit obtains a storage power of the auxiliary capacitor and then output to the DC to DC converter to keep the voltage of the storage capacitor at a preset voltage for a long time.
