摘要
目前输出滤波器多采用传统的LC无阻尼滤波,这种滤波方式在输出特别是空载或轻载时极易产生振荡,严重影响整个系统性能并产生电磁干扰问题。近年来新型的阻尼滤波因其性能有着极高的优越性被广泛关注,其中有多种电路拓扑可供选择,对其分析比较了解各种拓扑的各自特点。综合技术与成本考虑,L-CCR型阻尼滤波器更为优越。
Traditional undamped LC filter was often adopted in past. There are some weak points in this way, EMI （electro-magnetic interference） and vibration of output for example. Novel damped filter is drew attention for its better performances. Analyzes and compares several circuit topologies of the damped filters and find their own characterizes. Considering technique and cost, L - CCR filter is superiority to the else.
