Abstract

An adaptive space vector modulation approach to compensate the DC-link voltage ripple in a B4 inverter is examined in detail. The theory, design and performance of this PWM method are presented and the method effectiveness is demonstrated by extensive simulations and experiments. High-quality output currents are guaranteed by this approach even with substantial DC voltage variations that might be caused by unbalanced AC supply system, diode rectification of the line voltages and circulation of one phase current through the split capacitor bank. The application of this approach to induction machine drives is also discussed. It is concluded that the DC ripple effect on the B4 inverter output can be minimized by an adaptive SVM algorithm with the advantage of improving the response of the DC-link filter and the output quality is high
