Development of low‐cost PV array‐fed SRM drive‐based water pumping system utilising CSC converter

Abstract

The prime objective of this study is to achieve a highly efficient and reduced-cost configuration of a solar photovoltaic (PV)-based water pumping system using a canonical switching cell (CSC) converter employing a switched reluctance motor (SRM). A CSC converter with a maximum power point tracking controller utilises a continuous conduction mode (CCM), which helps in power optimisation of PV array and limiting the starting inrush current in the SRM by requisite control. The CCM operation of CSC converter considerably reduces the stresses on its components. The fundamental switching of a mid-point converter lowers its losses and it improves the system efficiency. The proper selection of perturbation size and initial duty ratio of CSC converter provide the soft starting to SRM drive. An experimental prototype of the proposed configuration is developed and it authenticates its suitability over varying irradiance and different environmental conditions.

Efficient solar‐powered water pump with single‐input dual‐output DC–DC converter employing four‐phase SRM drive

“…In contrast, a switched reluctance motor (SRM) can emerge as one of the best alternatives over traditional and PM drives. It has the simplest and most rugged construction [19] and could best be suited for applications like solar water pumps with everlasting performance without any degradation.…”

Bidirectional multiport solar‐assisted SRM drive for pure electric vehicle applications with versatile driving and autonomous charging capabilities

“…The last two decades have seen a lot of progress in increasing the efficiency of PV arrays and work towards reducing their cost [35]. A considerable amount of work is done in the area of PV powered drives and is available in the literature [29,32,36,37] but very few are based on integrating grid, PV panel, battery and SRM to achieve various modes of operation using a single converter with a minimum number of switches. In [37], an SRM-based multiport bidirectional drive for PV-assisted electric bus is discussed.…”

Low‐cost SRM drive system with reduced current sensors and position sensors

“…In [12], an annular winding bilateral linear SRM for low-cost linear transportation systems is presented. Second, the power converters with fewer power devices have been investigated [13][14][15][16][17][18]. In [13,14], a single controllable switch-based SRM drive for low-cost and variablespeed applications is presented.…”
