Power Factor Correction of Single-Phase Induction Motor Using Magnetic Energy Recovery Switch

Abstract

Magnetic energy recovery switch (MERS) has a function of automatic power factor correction of series connected load. The MERS is applied for a single-phase induction motor to improve the power factor. Two control methods of the MERS for power factor correction are described in this paper. Experiments were carried out and confirmed that the input power factor of a single-phase induction motor is improved.
