This paper describes the design processes for a 3-Phase Variable Frequency Drive (VFD) as broken up into two stages: The AC-DC converter and the DC-AC converter. It acknowledges three (3) design versions, all. The output of the motor drive is 3-phase pulse width modulation (PWM) ranging in possible operation frequencies from 0Hz to 13kHz. The frequency control circuit uses an Arduino Uno based of the ATMEGA 328p.
