A power factor corrected AC-AC inverter topology using a unified controller for high frequency power distribution architecture

This paper presents an AC-AC inverter for a high frequency power distribution architecture. The inverter includes a high frequency resonant inverter and a buck-boost power factor correction stage. A unified controller controls both the resonant inverter and power factor correction stages. Unlike other single stage power factor corrected inverter topologies, the proposed inverter system has reduced DC bus voltage stress for the universal input line voltage. The proposed inverter is found attractive in low power applications
