<p>A controlled rectifier circuit having a BJT (1) implemented as the controlled rectifier 'CR' and first (2) and second (3) turn-off transistors coupled respectively between the base and collector and base and emitter of the CR BJT (1) to rapidly remove stored charge from the collector-base junction of that CR BJT (1). The turn-off transistors may be implemented with BJTs, FETs, or related active electronic devices, and the polarity of the transistors may be the same or opposite to that of the CR BJT (1). Anti-saturation and drive current amplifying circuitry may be provided. A turn-off drive command may be delivered to an appropriate transistor via steering logic or an auto-steering configuration. The circuit is preferably implemented as an integrated circuit.</p> |
