Digital controller based multi motor drive using spwm

Abstract

Controlling the speed of an induction motor through stator side is vital in industries. Multi motor speed control (MMD) is one of the inevitable needs in electrical companies like mills, crane etc. Individual converter is triggered by Field Programmable Gate Array (FPGA) with single digital controller is used to control the multi motor in this work. Due to this controller price and manual work have been reduced. Now a days, many controllers in need of digital execution. Electrical machines requires Sinusoidal Pulse Width Modulated (SPWM) converters for vary the speed. The generation of SPWM is done by using FPGA in this work.
