Single-phase Variable Frequency Switch Gear

About our project

Single-phase variable frequency switch gear that will operate at an output voltage of 120 VAC with frequencies between 1-60 Hz will be designed, built, and tested.  The single-phase variable frequency switch gear will use a user-selected input frequency between 1 and 60 Hz and generate an output voltage with a constant Volts/Hertz ratio.

The single-phase variable frequency switch gear designed will contain components necessary for a variable frequency drive.  Successful design of single-phase variable frequency switch gear can be extended to three phases, which will pave the way for design of a variable frequency drive.  Variable frequency drives vary the speed of three-phase alternating current induction motors by varying the frequency and voltage supplied to the motor.  Variable frequency drives are important because they provide energy efficiency benefits to industries that consume large amounts of power operating AC machines.
