摘要
提出了一种集三相应急电源(EPS)和并联型有源滤波器(APF)一体的复合系统。该系统应用双向PWM变换器,采用DSP数字控制技术,可以实现两方面的功能,即对负载的应急供电和对来自非线性负载的谐波和无功电流补偿。分别阐述了电路结构和控制策略两方面,计算机仿真初步证实了该系统的可行性。
This paper proposes a combined three-phase emergency power supply system with a parallel active power filter. Based on a bilateral PWM converter using DSP digital control scheme, it can carry out two functions ： supplying the load with emergency power and compensating current harmonics and reactive power generated from the nonlinear load when it operates off-line. In this paper, the circuit configuration and control scheme are discussed,feascbity is primly verified by the computer simulation.
