Abstract
An electronic switch driver improves control of semiconductor switches in resonant power trains, improves ZVS operation, eases design challenges, improves manufacturability, and scalability of power converter design. Individual switch timing control is offloaded from the main power train controller, eliminating the effects of parasitic impedances and timing errors, particularly in high power, large power trains. Deployed locally at each controlled switch, the driver circuit includes logic to optimize ZVS operation of the controlled switch in steady state operation and ensures continuity of operation, e.g. during start-up and other conditions under which ZVS may not be achieved. The driver circuit may turn the controlled switch OFF quickly in response to an ON command, ON quickly in response to an ON command when predetermined conditions, e.g. ZVS, exist; and ON slowly in response to an ON command when predetermined conditions, e.g. ZVS, do not exist.
