- W4283216711 abstract "Abstract As a kind of precision power equipment, the uninterruptible power supply system (UPS) can supply power to the load through a DC-AC converter to ensure the uninterrupted power supply in case of grid failure. The voltage waveform output by the inverter has a decisive effect on the power quality, performance of the UPS system is determined by the power quality. Therefore, this paper aims to optimize the output power of the inverter from two aspects: on the one hand, the three-level space vector pulse-width modulation (SVPWM) technology is combined with the double closed-loop control system to improve the voltage waveform of the inverter; On the other hand, the PI parameters in the double closed loop are optimized by the particle swarm optimization (PSO) algorithm, the dynamic performance of the system is optimized, the adjustment time and overshoot are reduced, thus the control performance of the UPS system is improved." @default.
