Implementing a Frequency Inverter: Scalar with ATMEGA8 and mikroC

The aim of this work is to develop a three-phase frequency inverter making use of ATMEGA8 AVR microcontroller programmed in C language, based on mikroC having a IGBTs bridge as driver. Therefore, in addition to programming the hardware used is also given to the rectifying step, switching through a set of IGBTs and control in which the microcontroller implements a sine table that implements a lag of 120 degrees between each phase and allow variation the frequency applied to the motor and thereby to vary its frequency.
