摘要： An improved power converter employs two conventional charging and discharging switches operating in a complimentary mode and driven by a switch driver controlled by a power factor correction controller. The power converter is firstly improved with a blocking diode for blocking cross coupled short circuit paths to enable multiple converters to drive respective primary windings of an output isolation transformer, and is further modified with an absorption capacitor for providing a discharge path for a switching capacitor connected across the discharging switch so as to enable zero voltage switching of the discharging switch while employing conventional power factor correction, over voltage protection and current limiting. A plurality of improved power converters can be connected between respective input power sources and respective primary windings of the transformer with each converter independently providing power factor correction without cross coupling short circuit paths.

摘要： A modified DC-to-AC power converter accomplishes power transfer to a load with electrical isolation, zero-voltage and zero-current switching, using a transformer core resetting mechanism. The power converter contains two switching devices, a main device connected in parallel and a secondary device connected in series with a transformer primary winding. A secondary winding of the transformer is connected through a two-port resonant link circuit to a resistive load. Zero-voltage switching and proper transformer-core resetting are achieved from the resonance that exists between the parasitic capacitance of the secondary switching device and the magnetization inductance of the transformer. A transformer leakage inductance facilitates zero-current switching; thus, reducing the turn-on switching loss in the conventional main switching device. The switching converter contains a lossless clamping circuit, to limit the voltage stresses across both of the power switching devices to the reflected output voltage appearing across the primary.

摘要： A modified boost converter accomplishes power transfer to a load with an electrical isolation, a zero-voltage and a zero-current switching, a transformer core resetting mechanism, and component stresses identical to those in the conventional boost converters. The power converter contains two switching devices, a main one connected in parallel and a secondary one connected in series with a transformer primary winding. A secondary winding of the transformer is connected through an output rectifier to the load. Zero-voltage switching and proper transformer-core resetting are achieved from the resonance that exists between the parasitic capacitance of the secondary switching device and the magnetization inductance of the transformer. A transformer leakage inductance facilitates zero-current switching; thus, reducing the recovery time and current in the output rectifier, and the turn-on switching loss in the conventional main switching device. The switching converter contains a lossless clamping circuit, to limit the voltage stresses across both of the power switching devices to the reflected output voltage appearing across the primary.
