Abstract
A boost power converter for powering a load with an AC power source. The boost power converter has an energy storage device, a resonant circuit, a resonator switch circuit, a boost inductor circuit with a boost inductor, and a boost switch circuit. The resonator switch circuit alternately connects the resonant circuit to different sides of the energy storage device, where power from the energy storage device is transferred by the resonant circuit to the load. The boost switch circuit selectively connects the boost inductor to the resonator switch circuit, such that the boost inductor is charged in one of two different directions depending on the phase of the AC power source. The boost power converter is well-suited for ballast applications that drive a fluorescent lamp.
