摘要
有源滤波器补偿电流的传统检测方法中,由于锁相环存在零点飘移、假锁、失锁等问题,造成基准信号的相位误差,提出了采用无锁相环的检测法检测谐波电路。仿真结果表明,与传统方法向比,该方法简单可靠,降低成本。
The problems such as zero detecting method because of the phase ticle proposes one new method without also made the circuit more simple and drifting, false lock, lose lock exist in the traditional harmonic current lock loop （PLL）. These problems could result in phase error. This article proposes one new method without PLL. The MATLAB simulation proved that it not only saved cost, but also made the circuit more simple and reliable.
