Abstract
A capacitive ignition system for an internal combustion engine includes a voltage converter which has two primary terminals and two secondary terminals a primary voltage source has two voltage source terminals (A+, A−) which are connected in each instance to one of the primary terminals so that a primary circuit is formed; a switch which is incorporated within the primary circuit and a controller so that the switch can be closed and opened; a first control device constructed to actuate the controller in accordance with an ignition pattern for closing and/or opening; an electrical capacitance (C1, C2) within the primary circuit; and a second control device (25) constructed to maintain constant a voltage rise at the secondary terminals, which occurs in order to reach the ignition voltage, as the ignition energy requirement of an ignition device connected to the secondary terminals changes.
