N2 - In order to compensate dead-time effect of PWM voltage-source inverter, a novel dead-time compensation strategy with zero-current clamping phenomenon eliminating is presented. On the base of analysis for dead-time effect, the method based on error-voltage vector compensation is adopted. To improve accuracy of current polarity detection, the components of magnetizing current and torque current are filtered and then transformed into two axes stationary frame. In addition, to improve the output current waveforms, the zero-current clamping effect is compensated in the stationary frame combining with the above dead-time compensation method. The proposed compensation scheme is realized with TMS320F2812 DSP chip. Experimental results demonstrate the feasibility of the dead-time compensation method in 11kW vector controlled induction motor drives.
