| 摘要 |
A frequency converter having a silicon controlled rectifier comprises a protection circuit which includes a series resonant circuit connected in parallel with the silicon controlled rectifier to generate a reverse voltage thereacross in response to a short circuit established in response to a commutation failure of the silicon controlled rectifier. An inhibit circuit is provided to respond to the reverse voltage by inhibiting the current flow through the silicon controlled rectifier to allow the same to restore to its locking state. |
