A Practical Technique for Power Quality Improvement for Single Phase Induction Machines

Abstract

Most of the electrical loads in our daily life are single phase as well as inductive. Single phase induction machines are one of the many reasons for poor quality power supply along with some concerns on torque requirements, accelerating time, starting current, dip in voltage and harmonics in input current. During starting, power supply is more adversely affected. This paper presents an analysis of all the above mentioned problems along with a practical way to mitigate them. The results and tests performed before and after application of the proposed solution have been analyzed and presented. The conclusions presented in this paper will stimulate and direct future research work for maintaining high quality power supply during starting of induction machines.
