Abstract
The invention concerns a low voltage-to-high voltage converter of the flyback type. The converter includes a transformer whose primary winding is linked to a supply voltage source via a switch and whose secondary winding is linked to the terminals of a capacitor via a rectifier diode. This converter includes, in a conventional manner, a secondary regulation loop which compares the output voltage appearing at the terminals of the capacitor, via a divider bridge, with a reference voltage in order to regulate the OFF time of the switch. Provision is made to maintain constant the primary energy accumulated in the transformer and the total charge time of the capacitor, regardless of the value of the supply voltage. Digital regulation of an open loop system is employed to control the ON time of the switch on the basis of the value of the supply voltage and the temperature of the converter. The invention finds particular utility in high-energy projectile firing systems.
