ripple frequency

Contrasted with traditional cycloconverter without logical circumfluence, the new cycloconverter fed drive system not only eliminates reactive power impluse to electric network, but also heightens upper frequency of maximum output current and reduces output ripple current.

与传统的逻辑无环流交交变频器相对比，不但消除了变频器对电网无功的冲击，而且提高了最大输出电流的频率上限，减小了输出脉动。
