| 20120127769 | Soft Switching Power Converters - Soft switching power converters are described. In one example, a grid tie solar power converter includes an input for receiving a direct current (DC) power input, an h-bridge coupled to the input, and an output coupled to the h-bridge. The h-bridge includes a plurality of power switches. The output includes a first output node and a second output node. The converter also includes a first output inductor coupled between the h-bridge and the first output node, a second output inductor coupled between the h-bridge and the second output node, and a soft switching circuit coupled to the first output inductor and the second output inductor. The soft switching circuit is configured to facilitate zero voltage switching of the plurality of switches of the h-bridge. | 05-24-2012 |
