A multilevel inverter with a H-bridge clamp circuit is proposed for single-phase three-wire (1P3W) utility connected applications such as PV systems. The proposed inverter consists of two n-level inverters and a H-bridge clamp circuit. The proposed inverter requires only 12 controllable switches to obtain a 5-level output voltage though conventional multi-level converters with grounded neutral point...
A multilevel inverter with H-bridge clamp circuit is proposed for single-phase three-wire (1P3W) utility connected applications such as PV system. The proposed inverter consists of two n-level inverters and a H-bridge clamp circuit. The proposed inverter features high compatibility with next generation semiconductors because the uses of a high voltage H-bridge clamp circuit at grid frequency switching...
This paper proposes a new circuit topology for a multilevel pulse width modulation (PWM) rectifier. The proposed method forms a new circuit by combining a diode clamp-type topology with a flying capacitor-type topology. The proposed circuit uses only 12 switches, despite the use of a five-level three-phase PWM rectifier. Further, the proposed circuit can obtain good performance, same as a conventional...
