The present invention is related to power conversion circuits which are able to effectively reduce the current ripple and decrease voltage stress on semiconductor switch with minimum component count. Similar topologies may be used for rectification instead of inversion.
An object of the present invention is to provide a switching mode power converter having an inversion or rectification circuit for canceling current ripple.
Another object of the present invention is to provide a switching mode power converter having an inversion or rectification circuit with leakage inductance and capacitor being a lossless snubber for recycling the leakage energy. Consequently, the converter's efficiency can be improved.
A further object of the present invention is to provide a switching mode power converter having an inversion or rectification circuit with at least one pair of two series-connected lower voltage rating semiconductor switches accompanied with lower RDSON resulting in reducing the conduction losses. Consequently, further efficiency improvements can be improved.
