Capacitive discharge ignition exciter using SCR discharge switches. |
摘要 |
<p>An exciter circuit for a gas turbine engine ignition system. A high voltage supply continuously charges a storage capacitor. A plurality of silicon controlled rectifiers (SCRs) are connected in series between the storage capacitor and a high voltage conditioning circuit. A multi-section protective network is connected in parallel with the series connected SCRs. Individual network sections are connected across separate ones of the SCRs. The SCRs are normally non-conducting and are periodically triggered to discharge the storage capacitor into the conditioning circuit. An igniter plug is connected to the output of the conditioning circuit. The protective network divides the voltage of the storage capacitor equally across the SCRs when the latter are non-conductive thereby reducing the voltage stress to which each of the SCRs is subjected.</p> |
