In this study, we focused on to drive a compound DC motor with a Fuel-Cell and battery, which uses hydrogen as a fuel. A fuel cell can supply maximum 40V electric. In order to drive a DC motor, it needs 200Vdc. Therefore, a microcontroller controlled boost converter that is used to increase the voltage for desired level that is supplied with fuel cell and battery. During the powering process, the feedback control is implemented into the system with current and voltage sensors. So, the ATmega16U2 microcontroller is able to decide the desired duty cycle of the boost converter which is used for the gate of IGBT. Thus, the results presented in this paper with laboratory experiments.
