A phase-locked loop is really a feedback system combining a voltage controlled oscillator (VCO) and a phase comparator so connected that the oscillator maintains a continuing phase angle in accordance with a reference signal. To be able to synchronize two power generation systems with equal frequencies; synchronism must occur while voltages' phase angles of the systems will be the same. Phase angle of a three-phase system is set via phase locked loops. If three input phases are balanced, then custom phase locked loops detects phase angle appropriately. In present paper, a phase locked loop with proper controller is proposed which detects phase appropriately in balanced situation of input phases.
