中文摘要: 在有源电力滤波器(APF)设计过程中,需要实时检测谐波指令电流,基于锁相环倍频原理设计了一种基于硬件锁相环的同步采样方法,即锁相环倍频电路,实验结果表明:该锁相环电路能实现实时跟踪,且稳定可靠.
Abstract:In the desiging of APF, it is necessary to have real-time sampling of the DSP.Based on the principle of PLL, a synchronous sampling method is designed on the basis of PLL hardware, namely, PLL circuit.The result of experiment shows that this PLL circuit can meet the need of real-time tracing and has the effect of reliability.
