This paper presents a novel high-frequency isolated full-bridge inverter. The output dc voltage of renewable energy sources varies in a wide range. To obtain a regulated output ac voltage, a buck-boost inverter is used. The proposed inverter provides step-up and step-down operation in a single stage with a wide range of input voltage. It is implemented with a single output inductor, a high-frequency transformer for isolation and only one switch is switching at high-frequency at a time. The proposed inverter eliminates the need for a 50/60 Hz low-frequency transformers and thus improve the power density. To verify the operation, a hardware prototype with output voltage 110 Vrms, line-frequency 60 Hz, and output power 500 W is implemented and tested.
