摘要: Disclosed is a novel and innovative class of buck-boost bidirectional inverters achieve ultra high efficiency in applications requiring converting of one or more low and variable DC voltages of one or more power sources (which may include a battery, a low-voltage DC source, or a set of PV solar panels) to an AC voltage (e.g., connected to a grid) through a single-stage power conversion with step modulation.

摘要: An apparatus for providing a power output proportional to a source signal, including a phase modulator driving an upper and an lower power driver with carrier waveforms having a relative phase difference and having a signal modulated thereon, and coupled to a resonator circuit to operate as a substantially zero-voltage zero-current switching element, with the output fed into respective upper and lower transformers. Identical symmetrical secondary circuits on the transformers have a rectifier stage electrically connected to an inductor in series with an upper capacitor to form an upper low pass filter, and a high speed semiconductor switch coupled to a node between the inductor and rectifier stage provides a return path to ground. The lower secondary circuit inductor is highly coupled (>=0.99) to the upper inductor, and an output formed across the upper and lower output elements is isolated from rail voltage and balanced with bi-directional current.
