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。 At present, the output filter adopts traditional LC undamped filter, which can easily generate oscillations when the output is no-load or light-load, thus seriously affecting the entire system performance and generating electromagnetic interference. In recent years, a new type of damping filter has attracted a great deal of attention due to its high performance. Among them, there are many kinds of circuit topologies to choose from, and their respective characteristics of various topologies are analyzed and compared. Comprehensive technology and cost considerations, L-CCR damping filter is more superior.
