In order to ensure the safe operation of the power system harmonic pollution, it is necessary to undertake administrative, in order to improve the quality of power. Of the current industrial real character, restrain harmonics of the basic means is packed all kinds of filter compensation devices. Passive filter structure is simple, economical, but vulnerable network impedance and running state affecting and system in resonance, and only can compensate fixed frequency harmonics. And active filter may solve these problems, and can be used to monitor the changes of harmonic compensation, highly controlled, thus has the high development prospects. The main content of this article are: 1. The voltage controlled voltage source second-order active band-pass filters theory, including its mathematical model and the typical parameters, 2. Introduce integrated op-amp muon A741 structure, pins and performance parameters, 3. Software protel 99 and multisim brief introduction, 4 the basic knowledge of welding, 5. Design, make a second order voltage controlled voltage source filter, and carries on the test. Key words: vol
