On this paper, digitally controlled push-pull dc-dc converter and dc-ac inverter for induction motor control are presented, which is used one DSP(digital signal processor). This system has 12V battery input for the push-pull converter, and the push-pull converter generates 300V output for induction motor inverter input. In order to compensate the push-pull converter, the transfer function of push-pull converter is derived and digital PI compensator is adapted. Through bode diagram, stability of digitall controlled push-pull converter is analyzed. To verify the proposed system, digital simulation of the induction motor drive using digital push-pull converter are performed.

On this paper, digitally controlled flyback dc-dc converter and dc-ac inverter for bldc motor control are presented, which is used one processor. This system has 12V battery input for the flyback-converter, and the flyback-converter generates 30V output for BLDC motor inverter input. In order to compensate the flyback-converter, the transfer function of flyback converter is derived and digital PI compensator is adapted. Through bode diagram, stability of digital flyback-converter is analyzed. To verify the proposed system, digital simulation of the bldc motor drive using digital flyback-converter are performed.
