Modulation Technique for Single-Phase Transformerless Photovoltaic Inverters with Reactive Power Capability

Modulation Technique for Single-Phase Transformerless Photovoltaic Inverters with Reactive Power Capability Abstract: This paper underpins the principles for generating reactive power in single-phase transformerless photovoltaic (PV) inverters. Two mainstream and widely adopted PV inverters are explored, i.e., H5 and HERIC. With conventional modulation techniques, reactive power cannot be realized in H5 and HERIC due to […]


Modified Single-Phase Single-Stage Grid-tied Flying Inductor Inverter with MPPT and Suppressed Leakage Current

Modified Single-Phase Single-Stage Grid-tied Flying Inductor Inverter with MPPT and Suppressed Leakage Current Abstract: In this paper, an improved transformer-less single-phase single-stage grid-tied flying inductor inverter is presented. The negative terminal of the PV panel is grounded in the proposed topology, which increases reliability and suppresses the leakage current. The proposed topology has buck-boost capability […]
