Components, systems and methods for generating variable frequency AC voltage from a DC power supply are described. The components include a full-bridge (FB) parallel load resonant (PLR) converter which operates in discontinuous conduction mode. The PLR converter includes MOSFETs in an H-bridge configuration and employs a topology which minimizes inductance. The PLR converter can be coupled to a single or poly-phase bridge for use as an inverter. The inverter can be used to produce an AC sinusoidal waveform from a low voltage, high current DC power supply. Systems and techniques for modulating the output from the PLR converter to produce an AC sinusoidal waveform having desired characteristics, including frequency and voltage, are also provided. The PLR converter can also be coupled to a rectifier for use as a DC-DC converter.
