In this paper, we propose the dead time effect compensation algorithm using proportional resonant controller in pulse width modulation inverter of motor drive. The dead time causes the control performance because of the output current distortions. To solve these problems, the output current including ripple components are analyzed. A new dead time effect compensation algorithm using proportional resonant controller is proposed to reduce the output current harmonics.
