    Abstract: A wireless power transmission circuit for wirelessly transmitting line frequency sinusoidal AC power to a load where the line frequency ripple filter of conventional circuits is eliminated and a DC-to-AC inverter is replaced by a simple polarity inversion circuit. The envelope of the high frequency AC on the AC line frequency source side is not constant but varies continuously in a half-sinusoidal fashion at the line frequency. Wireless transmission occurs only with a half-sinusoidal, constantly varying envelope, not the constant amplitude envelope of prior art. High frequency rectification and high frequency ripple filtering occurs as in the prior art but the ripple filter time constant is selected so that resulting waveform is an accurate replica of the rectified line frequency voltage present on the transmitter side. A polarity inversion stage replaces the DC-to-AC inverter of conventional art to generate the line frequency AC.

    Abstract: Methods and systems for managing link voltages in a power converter, where single phase, three phase or universal systems can be used. Common mode management refers to shifting of voltages in a particular direction to perform transition between input and output ports, in addition to maintaining soft switching property. Voltages in power converters can be freely increasing and decreasing, and thus damage to the circuit can be caused if these voltages change are not controlled.

    Abstract: Methods and systems for power conversion. An energy storage capacitor is contained within an H-bridge subcircuit which allows the capacitor to be connected to the link inductor of a Universal Power Converter with reversible polarity. This provides a "pseudo-phase" drive capability which expands the capabilities of the converter to compensate for zero-crossings in a single-phase power supply.
