In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...

6.1 INTRODUCTION The previous chapters have discussed the development of the MPPT algorithm and the control of the DC-DC converter in a standalone PV system. A grid-connected PV system is composed of a photovoltaic array, DC-DC converter, DC link capacitor, single phase DC-AC inverter, filter inductor, power grid, and non-linear load. The grid interconnection of a PV power generation system has...

Three-phase three-wire Distribution Static Compensator (DSTATCOM) with Photovoltaic (PV) array or battery operated DC-DC boost converter is proposed in this paper. The proposed DSTATCOM consists of a three-leg Voltage Source Converter (VSC) with a DC bus capacitor and it provides continuous reactive power compensation, source harmonic reduction and load compensation throughout the day. With the...
