A capacitive discharge ignition system is described that incorporates a two-terminal passive network for controlling the discharge of a capacitive energy storage device into an igniter plug, wherein the network comprises a solid-state switch for alternately providing high and low ohmic paths between the two terminals in order to selectively connect the capacitive energy storage device to the igniter plug. The passive network includes means responsive to a predetermined value of a voltage differential between the two terminals for effecting the switching of the path between the two terminals provided by the solid-state switch from a high ohmic value to a low ohmic value, thereby controllably discharging the capacitive energy storage device into the igniter plug. In the illustrated embodiment, the solid-state switch is a series of SCRs, each of whose anode is connected to the trigger input of the SCR by way of a breakover diode.
