Design of Unity Power Factor Controller for Three-phase Induction Motor Drive Fed from Single Phase Supply

This paper carves out the design of unity power factor controller for three phase variable speed induction motor drive. SPWM technique is used to improve the power factor of the system to unity and hysteresis controller is used for speed control of the drive. These control techniques lead to a unity power factor seen by the ac supply and minimize the power loss, audible noise, and motor torque ...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

A Novel Stand-Alone Single-Phase Induction Generator Using a Three-Phase Machine and a Single-Phase PWM Inverter

A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...

Three-Phase to Single-Phase Matrix Converters: New Topology Based on New Control Method

In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...

A Traction Three-Phase to Single-Phase Cascade Converter Substation in an Advanced Traction Power Supply System

The advanced traction power supply system (ATPSS) is a new directional development for traction power supply systems, which can totally remove the neutral sections and effectively promote power quality. However, the existing converters suffer from small substation capacity. In this paper, a new configuration based on a three-level neutral point clamped (3L-NPC) three-phase to single-phase casca...
