This paper presents the design and testing of a boost type DC/DC converter circuit, which can be used for DC motor control applications. The Boost converter is designed using DC chopper and DC chopper cascade configurations. The experimental setup was made by connecting the boost converter circuit with four types of DC motor, i.e. self-excited DC motor shunt, series, compound and separately excited DC motor. The motor was then coupled with a powderbreak as the load. The testing results show accepted performance, where the DC motor speed can be increased due to the increments of the output voltage of the DC/DC converter. The performance test comparison between the DC chopper and DC chopper cascade has presented that both converters have almost the same capability to drive the DC motors. Without load, the DC/DC converter can drive the DC motors to rotate at about 440 rpm at 15V dc supply and 1400 rpm at 55V dc supply. Coupling the motor with load will decrease the motor speed at about 346 until 505 rpm, depending on the load torque value and the DC motor type.
