Abstract

This paper presents 250W, 50 KHz LCC resonant inverter having Efficiencies greater than 90% were obtained down to resistive loads of 50%. Efficiencies greater than 75% were obtained at significantly reduced loads (11%). Operation above resonance was utilized to increase the efficiency and maintain zero voltage switching (ZVS) for varied loads. Total harmonic distortion (THD) of less than 10% was achieved for all resistive loads. The evaluation version of PSIM was used to model the LCC topology for varied loads and LCC configurations. An LCC Resonant Inverter is proposed for applications in high frequency distributed AC power systems. The advantages of the LCC topology are low total harmonic distortion (THD) high efficiency and the ability to handle varying loads.
