Research and development concerning the electrification of the easily affordable two-wheel vehicle segments operating at low power capacity are significant for a highly populated country like India to attain sustainable transportation. Hence, a novel approach is proposed in this paper focussing on the investigation of bi-directional quasi-Z source...

Alternative energy sources have impacted as the ideal choice for reducing the burden on the grid and producing clean energy for water pumping. As an alternative to conventional motors for pumping, switched reluctance motor (SRM) is promising, cost-effective and highly efficient. This paper presents artificial intelligence (AI) supported variable vo...

Variable speed drives (VSDs)‐based direct photovoltaic (PV) fed water pumping systems (WPS) are of increasing importance for the socio‐economic growth in remote areas. Due to the absence of windings and magnets on the rotor, switched reluctance motor (SRM) is emerging as a viable economic alternative in VSD systems. Thus, this study proposes and pr...

A conventional power factor correction (PFC) based light emitting diode (LED) drivers composed of two-stage DC-DC conversions has several drawbacks such as; increased system size due to more component count, less efficiency, and complex control, etc. The grid powered LED lighting demand for high step-down conversion because the required voltage lev...

Conventional structure of PFC AC-DC converter integrated with DC-DC converter is used in electrical vehicle and battery charging applications. AC-DC converter is to convert AC voltage to specify DC level with near to unity power factor and DC-DC Bidirectional converter is used to charge and discharge the battery at specified operation. These conver...

Variable speed drives for PV-fed water pumping system (WPS) in rural areas prove highly promising for economic and social growth. Being more economical without winding and permanent magnets on rotor, switched reluctance motor (SRM) is emerging as an attractive option in variable speed drives. Such a system demands for a suitable controller with sim...
