Renewable energy-fed switched reluctance motor for PV pump applications

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

“…The SRM requires only unipolar currents allowing the design of a low-cost converter with one controllable power switch per phase [7]. The simple, rugged and compact structure, low inertia, large acceleration capabilities, high efficiency and fault tolerance capability of SRM, make it perfect for SPWPS [8][9][10]. Among various possible configurations of SRM drive, a four-phase arrangement with a mid-point converter is the most efficient compact due to its various benefits [8].…”

“…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.…”

“…Some of these arrangements have utilised a number of sensors for motor control. 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.…”

Design of solar‐powered agriculture pump using new configuration of dual‐output buck–boost converter

“…Some researchers have also carried out the investigation of permanent magnet brushless DC (BLDC) motor and permanent magnet synchronous motor (PMSM) used water pumping [13][14][15][16]. Although these motors offer the high efficiency and low maintenance obligation, the major constraints with BLDC motor and PMSM are their slender reach for constant power action and reasonably expensive due to the existence of PM materials [17,18]. Contrasting permanent magnet motors and conventional motors, the SRM does not need costly magnets or rotor winding and is very simple and rugged.…”

“…In the reported literature where SRM is utilised for PV-powered water pumping [17][18][19][20][21][22], a well-made arrangement is examined in [18], where a three-phase SRM drive is employing to run solar PV energised water pump with a battery storage. The system includes a 6/4 pole, three-phase SRM with high-frequency switching of Miller SRM converter.…”
