Abstract

Computer analysis and control method aimed at eliminating a DC content in the output currents of a 3-phase pulse-width modulated (PWM) inverter supplied by an unbalanced split- source DC voltage bus and used in an aerospace application is presented. After a thorough examination of the problem, from which a particular case associated with the non-zero DC current content has been identified, a control scheme is proposed for both sinusoidal and space vector PWM inverter whereby DC components in the inverter load currents are removed.
