In this study, the equality of frequencies and phase angles for the parallel connection of generators have been achieved using microcontroller. The study firstly provides the equality of frequencies and then the equality of phase angles. Waveforms of alternating voltages are converted into square wave using the zero crossing circuit after conditioned by the AC/AC signal sensing circuit. These signals are matched in order to arrange the DC motor's velocity with changing it's duty ratio until alternator signal is equal to the reference signal by the PIC16F877 microcontroller and the program written in C programming language. When the utility and generator signals are equal to each other, the equality of frequencies is provided. After that the duty ratio is increased in stages until the angular difference decreases to 0 and the equality of phase angles is also provided.
