Abstract
This paper presents a control system of a microcontroller MC3PHAC phase induction motor rotor cage. Asynchronous motor power is achieved through a static frequency converter. It consists of a rectifier circuit, a filter and a three-phase inverter power transistors made with IGBT type. Phase inverter is controlled using microcontroller preprogrammed MC3PHAC generates six PWM signals for controlling the power switches of the inverter. The system was designed and developed practical laboratory electric car in the Faculty of Engineering of Bacau. Commissioning and tests conducted have given good results.
