Abstract
In this paper, a dc link voltage variable inverter system is proposed, which consists of a two-switch buck-boost converter and a four-switch inverter. In addition, as the current and torque ripples are generated by a voltage difference between back EMF and dc link voltage, these ripples could be reduced according to the controlled dc-link voltage according to the motor speed. The validity of the proposed inverter is verified by informative simulation and experimental results.
