A circuit for igniting and sustaining an electron discharge includes an ignitor circuit. The igniter circuit includes a high voltage transformer and a switch connected in series between a primary of the transformer and a DC source return. The switch is configured to receive a driving signal. A reset circuit is connected in parallel to the primary of the high voltage transformer. A first rectifier is connected in series between a secondary of the high voltage transformer and a keeper. A terminal of the secondary of transformer is connected to a cathode. The circuit for igniting and sustaining the electron discharge also includes a sustaining circuit having a current source with a return connected to a cathode and a second rectifier connected in series between the current source and the keeper.

    一种用于点火和维持电子放电的电路包括点火器电路。该点火器电路包括高压变压器和串联连接在变压器的初级和DC源回路之间的开关。开关被配置成接收驱动信号。复位电路并联连接到高压变压器的初级。第一整流器串联连接在高压变压器的次级和保持器之间。变压器的次级的端子连接到阴极。用于点火和维持电子放电的电路还包括维持电路,该维持电路具有带有连接到阴极的回路的电流源、和串联连接在电流源和保持器之间的第二整流器。
