Power converter for high efficiency high frequency resonant gate driver

摘要

(57) during switching (Sa, Sb) of power switching one or more devices, high-frequency switching circuit for driver circuit, such as a converter for the [summary] gas discharge lamp, and the input capacitance of the parasitic of the power switching device and includes a resonant circuit for exchanging energy. I will be blocked by the exchange of this energy, capacitive energy that could destroy one or more components of the driver circuit is also not to be consumed by the driver circuit. Resonant circuit of the driver circuit is equipped separate inductors and (Lx). It is preferred providing (Cxa, Cxb) also discrete capacitors of one or more driver circuit, it is to to maintain resonance at a predetermined frequency regardless of changes in the input capacitance of the parasitic.
