A Single-Stage Differential Boost Inverter with Modified SPWM Control for BESS Applications

The research proposes the single stage differential boost (SSDB) inverter for the single stage battery energy storage system (BESS) in which the topology can transfer AC source supply AC load. This study the single stage circuit architecture let reduce the cell number and enhances the system performance. This work proposed modified sinusoidal pulse width modulation (PWM) to control the SSDB inverter and the proposed control method significantly improved the total harmonic distortion (THD) of the SSDB inverter output voltage. Finally, compare of the PWM and proposed control method that the proposed control method THD is better than the PWM and improves the SSDB inverter output voltage quality.
