Proposal of Boost converter without reactor using Open-ended Winding PMSM for Photovoltaic Pump System

The way to use of clean energy is promoted actively, improving this system is important to solve environment issues. In photovoltaic pump system, voltage to work that system is generated by chopper circuit. However, in this system, there is problem that increase of cost and upsizing by chopper circuit for boost converter. In this paper, we propose the system to replace a reactor in chopper circuit with three phase windings of the open-ended winding PMSM.
