Design and Development of Self-Assisted Switched Reluctance Motor Driven Solar Water Pump

Self‐governing single‐stage photovoltaic water pumping system with voltage balancing control for a four‐phase SRM drive

“…A complete assessment of these systems in different aspects is organised in Table 1. The losses at different stages in conventional systems [15,16] and the proposed system are given in Fig. 13.…”

“…Moreover, the voltage balancing technique used to equalise the voltage across two split capacitors of mid‐point converter for four‐phase SRM drive further helps to reduce the capacitor size and torque ripples. To show the efficiency comparison between conventional two‐stage [15], single‐stage [16] and proposed systems, the efficiency of each is estimated at different insolation levels under similar working conditions depending on experimental investigation. While the power losses in the water pump are not involved in the efficiency estimation.…”

“…Given various advantages of SRM drive in SPWPS, many publications have examined the performance of different configurations of SRM drive for water pumping application [8][9][10] and [13][14][15][16]. All these configurations can be classified into two major categories.…”

“…The inverters involved to excite the SRM windings have low-energy feedback with higher components in this system [8][9][10]13]. Although, the system discussed in [14,15] has used a fundamental switching technique to commutate the SRM windings and have low sensor requirement. The presence of the DC-DC converter and the utilisation of conventional MPPT technique results in a lowefficiency system with slow dynamic response and high-rated DClink capacitors.…”
