Design & Analysis of Power Electronic Converters for Renewable Energy

This book presents a comprehensive study of advanced power-electronic converters, multilevel inverters, electric drives, renewable-energy integration, and electric-vehicle charging systems. It brings together three complementary chapters covering the design, control, analysis, and performance evaluation of modern power-electronic systems. The first chapter focuses on a five-level Cascaded H-Bridge Multilevel Inverter (CHB-MLI)-fed induction motor drive for grid-connected and PV-based applications, including isolated DC-source generation, SIMO flyback conversion, solar water pumping, and advanced THITRPWM modulation. The second chapter examines the progressive development of BLDC motor control from PI and Hysteresis Current Control to Field-Oriented Control and Sliding Mode Control, culminating in a hybrid FOC+HCC+SMC strategy for improved dynamic performance and reduced torque ripple. The third chapter addresses a PFC-based EV battery charger using a bridgeless isolated Cuk-SEPIC converter, emphasizing power quality, galvanic isolation, controlled charging, and performance under grid-voltage variations.
