DC-DC converter is a tool that use to regulate static dc voltage become variable DC voltage. This full bridge converter was designed using center trap trafo where the voltage income value increased until 2,5 times its income voltage after rectified with MUR1560 diode, so that the voltage recieved by the load is DC voltage. The load used by this research was permanent magnetic DC Motor with ½ HP power to adjust the speed of permanent magnetic motor with adjusting the pulse widht (duty cycle) PWM signal (Pulse Widht Modulation) resulting from signal generator like Atmega 8535 microcontroller. The method used in PWM switching process was PWM Phase Correct method. Signal generator with Atmega8535 microcontroller and optocoupler serie as the protection serie between control series and power series. The using of switching component and linear passive component and also transformator center tap affects the outcome voltage result in this theis design. The researcher did observation from duty cycle 5% to 20% with maximum outcome voltage 19v with 2654rpm motor speed, Caused by a leak in the transformer inductance causing the opponent .
