An Improved Zero-Current-Switching Single-Phase Transformerless PV H6 Inverter with Switching Loss-Free

An Improved Zero-Current-Switching Single-Phase Transformerless PV H6 Inverter with Switching Loss-Free Abstract: In this paper, a switching loss-free (SLF) concept for the first six-switches H-bridge inverter (H6-I) topology is proposed. SLF means that its switches are able to operate with soft turn-on and turn-off transitions. In order to implement the SLF goal, a new resonance-trajectory […]


A Single-Phase Transformerless Inverter with Charge Pump Circuit Concept for Grid- Tied PV Applications

A Single-Phase Transformerless Inverter with Charge Pump Circuit Concept for Grid- Tied PV Applications Abstract: This paper proposes a new single-phase transformerless photovoltaic (PV) inverter for grid-tied PV systems. The topology is derived from the concept of a charge pump circuit in order to eliminate the leakage current. It is composed of four power switches, […]
