Pulse Width Modulation
From developed simple pwm signal software, upper and lower switch of pwm simulations are obtained on digital oscilloscope as seen below;

PWM signals will be generated by a software we develop on the PIC 18f4431
After these 6 signals are generated we supply them to the optocoupler to seperate to low voltage power from the high voltage (power) part.
We decide to use a motor driver of the type IRAM 136-3023B i motion series
In the inpot side we build 3 rectifiers to obtain 3 different DC voltages with separate grounds.
