Abstract
A system includes a two-channel inverter for receiving a non-zero variable input voltage, first and second input channels each electrically coupled to the two-channel inverter, a transformer having a primary winding in electrical communication with the first and second input channels and secondary windings, and an active resonant circuit in electrical communication with the secondary windings for generating a switching output voltage at each of two different voltage levels. The active resonant circuit includes switching devices arranged in an anti-parallel configuration, a capacitor electrically coupled in series with the switching devices for receiving and storing energy during a first portion of a resonance cycle and for discharging the energy during a second portion of the resonance cycle, an inductor electrically coupled in series with the capacitor and the switching devices for transferring the energy to and from the capacitor during the resonance cycle, and an output.
