Abstract
A method and apparatus are taught for driving a gate of a power device to turn on the power device utilizing a lossless gate driver circuit. The circuit comprises in parallel a power section, a rectifying section, a switching section, a capacitance, and an anti-spiking section. The circuit further comprises a transformer section coupled to the rectifying section, the switching section, and the anti-spiking section and a power device coupled to a portion of the anti-spiking section. The system is configured to regenerate substantially all energy utilized to power the power device via the coupling of the transformer section to the rectifying section, the switching section, the capacitance, and the anti-spike section.
