Abstract
In this paper, a new reduced device count (RDC) of 3-Ph, 3-L switched capacitor (SC)-based grid-connected inverter (GC1) with LCL filter has been elucidated. In this topology, a common single DC source has been connected to all phases and comprises four unidirectional switches, one discrete diode, and one switched capacitor per phase. It has the capability to produce three levels in pole voltage and five levels in the line voltages. Here, with parallel–series technique, all the switched capacitors are self-balanced without need of any separate balancing circuits/sensors. With respect to single DC source, the respective line voltage provides two times boosting ability in the inverter structure. The topology provides less per unit total standing voltage (TSV) and also provides an equal amount of blocking voltage across all semiconductor devices. At the end, for higher ripple attenuation purpose, an LCL filter has been integrated with grid. The combination of dq-frame current control strategy and unipolar phase disposition (UPD) pulse width modulation (PWM) technique has been applied to the GCI, and with this, the unity power factor (UPF) operation of grid has been elucidated vividly. Finally, the operation of an inverter and control structure has been validated through MATLAB/Simulink platform.
