| 摘 要： | 提出了大功率不间断电源(UPS)并机的一种同步均流控制方法,UPS通过追踪综合同步信号实现并机系统同步;通过调整输出电压的有效值,使其在稳态下负载电流均分,并且计算每个载波周期内输出电流与平均负载电流的瞬时值差,以此微调输出电压的瞬时值,大大增强了均流控制的动态性能.32位DSP TMS320F2812保证了锁相和采样... |

| Abstract: | This paper proposes a synchronous and current-sharing control method for paralleled high power uninter-ruptible power system(UPS).The paralleled UPS system operates synchronously depending on tracking with the syntheti-cal synchronous signal.Load currents are shared on steady state through adjusting virtual values of output voltages.In every carrier period,the instantaneous difference between output current and the mean of load current is measured to trim the instantaneous output voltage,which enhances the dynamic characteristic of current-sharing control.TMS320F2812,32 bit DSP,ensures the phase-locked and sampling precision.Testing results on prototype verify the validity of this method. |
