N2 - This paper proposes a single-phase bidirectional three-level T-type inverter. The proposed inverter has a T-type switching leg and a half-bridge switching leg. The T-type switching leg operates at high switching frequency with sinusoidal pulse width modulation. The half-bridge switching leg operates at the grid frequency according to the voltage polarity of the grid. Due to the three-level switching operation of the proposed inverter, it provides the advantages of low voltage stress, reduced switching loss, and low harmonic components for the single-phase gird-tied applications. The proposed inverter is introduced by describing its circuit configuration, switching technique, operation modes, and control scheme. A 1.0 kW prototype has been designed and experimentally tested to verify the performance of the proposed inverter.
