Some of the necessary characteristics needed for field-oriented AC drives square measure a quick run-stop capability and sensible speed regulation in spite of explosive load amendment. once connected to main power provide, induction motors run at their rated speed, but there square measure several applications wherever variable speed operations square measure needed. though a variety of induction control techniques square measure accessible, generating variable frequency provide may be a widespread management technique, having a continuing voltage to frequency quantitative relation so as to realize constant (maximum) force throughout the in operation amount. This management technique is named as variable frequency management. the most aim of this academic degree project paper emphasizes on the event of a general purpose universal board that's capable of dominant the speed of single or 3 part induction motor with minor package and hardware modifications. absolutely the system consists of the management, driver and therefore the power circuits. The negative feedback circuit includes the ability provide circuit and therefore the microcontroller. the ability circuit includes the full-bridge single-phase Pulse breadth Modulation electrical converter.
