The unipolar sinusoidal pulse width modulation full-bridge transformerless photovoltaic (PV) inverter can achieve high efficiency by using latest superjunction metal–oxide–semiconductor field-effect transistor (MOSFET) together with silicon carbide (SiC) diodes. However, the MOSFETs are limited to use in transformerless PV inverter due to the low reverse-recovery characteristics of the body diode...
The unipolar sinusoidal pulse width modulation (SPWM) full-bridge (FB) transformerless photovoltaic (PV) inverter can achieve high efficiency by using super-junction MOSFETs together with silicon carbide (SiC) diodes. However, the MOSFETs are limited to use in transformerless PV inverter due to the low reverse recovery characteristics of the body diode. In this paper, a new transformerless PV inverter...
