The emergence of wide-bandgap (WBG) power devices opens opportunities for current source inverters (CSIs) to provide a promising alternative drive configuration for motor drive applications. The sinusoidal output voltage of CSI offers significant advantages for numerous applications with long cables between the inverter and loads. This paper aims to compare the performance of the CSIs and voltage source inverters (VSIs) with sinusoidal output voltage. Hence, a sine filter is added to VSI for comparison purposes. In addition, a boost converter is added to VSI to match the voltage-boosting capability of the CSI. This paper presents a CSI-based motor drive system with a front-end DC/DC converter, specifically tailored for applications utilizing batteries as the power source, and then compares it with an equivalent VSI system with a boost dc/dc converter and output sine filter.
