Posted in: IEEE 2017, Power System
Single-stage Three-phase Current-source Photovoltaic Grid-connected Inverter with High Voltage Transmission Ratio Abstract: This paper proposes a circuit topology of a single-stage three-phase current-source photovoltaic (PV) grid-connected inverter with high voltage transmission ratio (VTR). Also, an improved zone sinusoidal pulsewidth modulation (SPWM) control strategy and an active-clamped subcircuit that can suppress the energy storage switch’s turn-off […]

Comments Off on Reactive Power Control for Single-phase Grid-tie Inverters using Quasi Sinusoidal Waveform
Posted in: IEEE 2017, Power System
Reactive Power Control for Single-phase Grid-tie Inverters using Quasi Sinusoidal Waveform Abstract: The paper presents a reactive power control technique for single-phase Photovoltaic (PV) inverters, especially unfolding inverters. The proposed system retains the benefit of the unfolding inverters having low material cost and semiconductor losses, and tackles the drawback of the standard unfolding inverter not […]
