INVERTER CIRCUIT WITH AVALANCHE CURRENT PREVENTION

摘要

An electronic circuit includes first and second inductive bias elements coupled to respective first and second switching elements for preventing avalanche current flow through the switching elements. In one embodiment, a resonant inverter circuit includes first and second switching elements with first and second freewheeling diodes coupled across the respective switching elements. A first inductive bias element is coupled to the first switching element and a second inductive bias element is coupled to the second switching element. The first and second bias elements are inductively coupled with a resonant inductive element for biasing the respective first and second switching elements against avalanche current flow.
