Abstract
A voltage controlled bridge is coupled to a line voltage and a transformer primary harmonic voltage, and a current controlled bridge is coupled to a line current and a transformer secondary harmonic voltage. A synchronous average harmonic current compensator integrates error between a measure of bridge current and commanded current synchronously over each half of a switching period and samples compensator output to control line current and linearize harmonic coupling between isolated bridges. A synchronous pulse width modulation process tracks commanded line voltage. One or more of a primary harmonic command circuit and secondary harmonic command circuit adjust the harmonic coupling voltage of the voltage controlled and current controlled bridge respectively. Line voltage, line current, and primary and secondary harmonic commands provide generalized line and isolated voltage bus regulation degrees of freedom in a single stage.
