CVCF逆变器用功率滤波器的设计

Design of Power Filters for CVCF Inverters

本文从理论上导出了CVCF逆变器用功率低通滤波器的设计公式,并讨论了实际情况下滤波器截止频率和标称特性阻抗的选择问题,提出了小容量(<1KVA)时功率滤波器标称特性阻抗选择的经验公式,最后给出了工程设计实例。

Design formula of low-pass power filters used for CVCF inver- ters is deduced theoretically.Selections of cut-off frequency and cha- racteristic impedance of filters in practice are discussed and a for- mula from experience to select characteristic impedance of filters un- der small rating is given.In the enda design example is presented.
