Resonant power conversion techniques are examined and applied to high-frequency link inverters. A novel control principle using two high-frequency inverters modulated in phase to produce a dc isolated carrier containing wanted output on its sidebands is discussed. This power signal, when rectified, filtered, and inverted, results in sinusoidal outputs at utility frequencies. The method is analyzed for both dc and ac outputs and is demonstrated with a 3-kW high-frequency link inverter feeding both resistive and utility interactive loads. Typical waveforms are illustrated and performance is discussed.
