Static-controlled current-source AC/DC power converter and DC/AC power converter, and protection system embodying the same |
摘要 |
In a current-source GTO converter, protection against a DC fault or a commutation fault condition is provided by immediately interrupting the conduction of a GTO device which is ON and by turning ON another GTO device to allow fault current to bypass the bridge or safely pass through the bridge. As a result, protective action is immediate and an early recovery is made possible. Bypassing of the bridge is done by freewheeling, with an auxiliary GTO switch or with one of the main GTO switches. Diversionary action is done through the bridge by changing the mode of operation of the bridge from rectifier to inversion, or conversely.
