有源逆变系统逆变失败的分析和强迫换流保护

Failure of the Line - commutated Inverter and the Imposed Commutation Protection

文章分析了有源逆变系统逆变失败的原因、表现形式、过渡过程,提出用强迫换流保护电路来解决问题,并给予实验验证。

This paper analyses the causes, forms and transidon processes of the failure of the line - commutated inverter and proposes an imposed commutation protection circuit. A prototype circuit is built to prove the operation principle of the circuit proposed.
