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.
