ABSTRACT:
This invention relates to a blocking oscillating converter for transferring energy from a source of power, such as a vehicle battery, to a storage means, such as an energy storage capacitor in a capacitor discharge ignition system. A novel control and feedback circuit incorporated in the blocking oscillator allows the drive level to the switching transistor to be controlled in response to the peak current in said transistor as well as the output voltage of the blocking oscillator. Furthermore the control circuit allows the blocking oscillator to be turned off during the short period of time after each spark discharge that is needed for turnoff of a switching device used to control that discharge.
