Posted in: IEEE 2017, Power System
A Medium Frequency Transformer-Based Wind Energy Conversion System Used for Current Source Converter Based Offshore Wind Farm Abstract: Offshore wind farms with series-interconnected structures are promising configurations because bulky and costly offshore substations can be eliminated. In this paper, a medium-frequency transformer (MFT)-based wind energy conversion system is proposed for such wind farms based on […]

Comments Off on Single-stage Three-phase Current-source Photovoltaic Grid-connected Inverter with High Voltage Transmission Ratio
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 […]
