Implementing a Soft starter: Based on ATMEGA8 and mikroC

The purpose of this work is to develop a three-phase Soft-starter making use of the AVR microcontroller ATMEGA8 programmed in C, based on mikroC and IGBT bridge as driver. Therefore, in addition to programming the hardware used is also shown in 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 growth gradually the effective voltage applied to the motor, thereby making the ramp ascent, descent and stable to place an induction motor in operation.
