    摘要: There is disclosed an arcjet starter for igniting and sustaining an electric arc in an arcjet thruster. The arcjet starter is capable of delivering a short duration, high voltage pulse for igniting the arc and then providing a continuous low voltage, high amperage current for sustaining the arc. The starter has two separate magnetics, one for initiating breakdown in the arcjet and another for sustaining breakdown during steady state operation.

    摘要: There is disclosed a power supply for igniting and sustaining an electric arc in an arcjet thruster. The power supply is capable of delivering a short duration, high voltage pulse for igniting the arc and then providing a continuous low voltage, high amperage current for sustaining the arc. A circuit in the power supply includes the combination of a low impedance inductor and a high impedance inductor. High voltage is blocked by the high impedance inductor for initiating the arc. As current begins to flow, the high impedance inductor magnetically saturates and the arc sustaining current flows through the low impedance inductor.
