A Single-Phase Grid Interfaced SRM Driven Irrigation Pump Using Vienna Rectifier for Power Quality Improvement

This paper presents a study focused on the solar-based switched reluctance motor (SRM) irrigation pump drive with a grid-support through a single-phase Vienna rectifier. Vienna rectifier is a unidirectional active power flow-controlled AC-DC converter with improved power quality. In this work, a hysteresis current controller (HCC) based Vienna control is used to draw grid current with minimum harmonics while maintaining the unity power factor (UPF) condition. Besides this, Vienna rectifier offers a three-level balanced DC voltage at the output with minimum ripple content, suitable for mid-point converter feeding the balanced supply to all the phases of SRM. The employed Vienna control ensures the grid-side power quality parameters follows the IEEE-519 recommendations throughout the operation and facilitates rated water discharge irrespective to the environmental conditions. The obtained results suggest that Vienna rectifier-based grid-interference provides an effective and reliable solution for solar fed irrigation pumps in compliance with the power quality norms.
