Cascaded Multilevel Inverter for Induction Motor Drive

In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Inducti...

Hybrid Cascaded H-bridges Multilevel Motor Drive Control

This paper presents a hybrid cascaded H-bridge multilevel motor drive control scheme for electric/hybrid electric vehicles where each phase of a three-phase cascaded multilevel converter can be implemented using only a single DC source and capacitors for the other DC sources. Traditionally, each phase of a three-phase cascaded multilevel converter requires n DC sources for 2n + 1 output voltage...

Drive Isolation Transformers--Solutions to Power Quality

Introduction The increased use of ac and dc motor drives in industrial plants has elevated the power quality application considerations associated with power distribution systems. These considerations have sparked great controversy about the use of drives in industrial applications and have raised questions about their effects on an electrical system. Valuable guide standards, such as IEEE 519-...

Design of Soft Switching Sepic Converter Fed DC Drive Applications

High efficiency DC-DC converters with high-voltage gain have been researched due to increasing demands. A soft-switching single-ended primary inductor converter (SEPIC) is presented in this work. An auxiliary switch and a clamp capacitor are presented in this project. A coupled inductor and an auxiliary inductor are utilized to obtain ripple-free input current and achieve zero voltage-switching...
