【 摘 要 】

This study aims to implement a single-stage differential boost inverter (SSDBI) applied in a single-stage battery energy storage system (BESS) topology that can supply power from a lower-voltage battery module to an alternating current (AC) load. Compared with the common two-stage topology, which has a two-stage converter and higher-voltage battery module array, the single-stage topology can reduce the number of cells and components and improve the power density. In addition, a modified sinusoidal pulse-width modulation (SPWM) control was proposed to reduce the control complexity of the SSDBI while improving the total harmonic distortion (THD) of the inverter. The modified SPWM control can reduce the duty ratio of the SSDBI and the stress on the components in order to improve the AC voltage output waveform and reduce the THD.
