Three phase induction motors have been considered one of the most commonly used electric machines in industrial applications due to their low cost, simple and robust construction. Existed six-switch three-phase inverters have been widely used in different industrial applications. These inverters have some drawbacks in low power range applications, which involve extra cost ,the six switches losses, and complicated control schemes. The main objective of research work to design new power converters for minimizing losses and costs have been proposed. The project objective describes a speed controller using a fuzzy-logic controller for indirect field oriented control of induction motor drives fed by a four-switch three-phase inverter. The proposed FLC improves dynamic responses and, it is also designed with reduced computation burden.
