Abstract: A system is described whereby floating capacitor H-bridge converters are located in each phase between the utility grid and a squirrel cage induction motor. Injecting a series voltage in ...

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

A squirrel cage induction motor must sense two or more electric phases to cause the magnetic field to start spinning, thus turning the motor’s rotor and shaft. Once the motor starts, the interaction ...

Troubleshooting single-phase refrigeration compressors requires a technician to have a proficient understanding of capacitors. The start capacitor is one of two types of capacitors that can be found ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Abstract: This paper presents the results of a study to investigate the use of IGBT hard-switched power electronics to soft start a squirrel cage induction motor when operating from the utility grid.
