本文将单周期控制方法扩展到电流源变换器的控制中，该变换器具有线性度好、精度高、瞬态响应快、电路参数设计方便等特点。串行混合有源电力滤波器（HAPF）是实现电流源的理想选择，在已报道的滤波器中具有突出的特点。推导了单周期可控电流变换器的工作原理；详细讨论了其在串联HAPF中的应用及控制方案。分析和仿真结果验证了该单周期可控电流变换器与电流型SHAPF相结合的可行性。这种SHAPF控制简单，电路简单，谐波抑制效果好。
This paper extends the one-cycle control method to control a current source converter, which has the natures of controllable current source including a good linearity, high precision, fast transient response, and easy design of circuit parameters. It is an excellent candidate to realize the current source in a serial hybrid active power filter (HAPF), which has prominent characteristics among the reported ones. The principle of the one-cycle controlled current converter is derived; and its application and control scheme in the serial HAPF is discussed in detail. Analysis and simulation results verified that the combination of this one-cycle controlled current converter and the current-type SHAPF is feasible. This kind of SHAPF is simple in both control and circuit, yet has good harmonic suppression.
