N2 - DC link voltage control is used to regulate the DC link voltage in cascaded architecture of Hybrid Electric Vehicle (HEV) motor drives that may be sufficient if DC link voltage changes in average sense only. Dynamically varying DC link voltage is required for 240-Clamped Space Vector PWM (240CPWM) that has a dominant component at six times the fundamental frequency (6f1) which requires fast control. Boost converter is usually used in the DC-DC stage whose bandwidth in voltage mode control is limited by right half plane (RHP) zero. In this work, voltage control with Smith predictor is proposed to shape the dynamic DC link voltage for 240CPWM that minimizes the impact of RHP zero. Efficacy of voltage control with Smith predictor in terms of better DC link waveshape tracking and low THD in load current are shown at maximum fundamental frequency of 300 Hz at 3 kW and compared with other well-known control methods.
