Along with the times, the application of renewable energy is increasingly being used, one of which is in the field of transportation. There are many means of transportation that use modern motors, such as switch reluctance motors and brushless DC (Direct Current) motors. BLDC motors or brushless DC motors have low mechanical losses because they do not use brushes like conventional dc motors. Because the brushless dc motor uses permanent magnets, a sensor is needed to determine the back-emf, apart from that for switching settings on BLDC motors using a three-phase inverter. In setting the output voltage on the three-phase inverter, it will produce a Pulse Width Modulation (PWM) output signal which will form 120° commutation. The excitation current of a brushless dc motor which is controlled electronically based on position feedback can produce ripple-free torque, however, if the motor is brushless dc. Therefore, this research will discuss the design of a three-phase inverter for BLDC motors using the six-step commutation method with ripple suppression to making prototypes using locally available materials.
