摘要/Abstract

摘要： 为在实验室环境下实现40 kW容量的船舶中压电力模拟试验系统,需要将380 V发电机组输出的交流电经电力变换得到稳定的4 kV直流输出。系统采用两级变换,前级AC/DC变换采用无桥boost型PFC(Power Factor Correction)电路,后级DC/DC变换采用四路全桥PWM(Pulse Width Modulation)变换器级联进行升压,其中一路为移相全桥完成调压控制输出,三路为普通全桥得到固定电压输出。在MATLAB/Simulink环境下对该AC/DC变换器系统进行了系统建模,仿真结果表明,该方案能输出稳定的4 kV电压,效率94.8%,纹波2.08%。

Abstract: In order to realize the simulation of marine medium voltage power system of 40kW capacity in laboratory, it is necessary to convert AC 380V of generators outputs to the stable 4kV DC output. Two level transformations were applied in the system. The bridgeless boost PFC circuit was applied in AC/DC conversion in front. Four roads of full bridge PWM converters in cascade mode were applied to boost the voltage in DC/DC conversion at the end. One of them was the phase-shift full bridge to achieve the control of adjusting voltage output. The other three bridges were common full bridge to get a stable voltage output. The simulation model of the AC/DC converter was established in MATLAB/Simulink circumstance. The simulation results show that it can output the stable 4kV DC voltage with 94.8% efficiency and 2.08% voltage ripple.

Key words: AC/DC converter, bridgeless PFC circuit, full bridge phase-shift converter, cascaded converter
