Abstract

One of the commonly used approaches to avoid the short circuit of power devices for pulse-width-modulation (PWM) inverters is to add dead-time into the control signals. The drawback of this approach is that severe distortion in phase currents and output voltages may occur. This paper proposes an adaptive-linear-neuron based nonlinearity compensation strategy to cope with the disturbance voltage caused by dead-time effects. In particular, by minimizing the feedback d-axis current error, the amplitude of disturbance compensation voltage Vdead is self-tuned using the least mean square algorithm. The dead-time compensation method developed in this paper does not need any information about electric parameters and phase current polarity. Moreover, the proposed approach is also free of complex mathematical computations and additional hardware. Experimental results indicate that the proposed dead-time compensation approach is feasible.
