Abstract

The conventional pulse width modulation dc to at inverters have a defect that all power devices are switched at high switching frequency. Therefore switching losses are significant. This paper proposed a dual-stage inverter that full bridge switches are operating at low output frequency while a high switching frequency are performed by a pre-inverter switch. The proposed inverter is shown to have small switching losses. Simulation and experiments are performed for verification.
