(WO9944269-A1)   NOVELTY - A charge pump (24), acting as an nth order voltage multiplier, increases the voltage available and continuously charge a capacitor (C2) to a level above the B+ supply voltage, enabling the stored energy of the capacitor to be boosted. The charged capacitor is selectively coupled to a voltage regulator (10) to maintain a constant regulator input voltage when the regulator input voltage falls to a predetermined level as a result of supply interruptions,    USE - A voltage supply circuit of the type which uses a capacitor to hold a charge for use in maintaining the supply during temporary supply interruptions. For electronic servo braking systems in vehicles, vehicle antilocking braking systems, vehicle engine management systems, etc.    ADVANTAGE - The physical size of the capacitor used in the ECU is smaller for a given performance, more easy to house securely and therefore more robust. The system is more capable of dealing with supply interruptions when an electrolytic capacitor of the same type is used. The rated working voltage and operating voltage of the capacitor can be equal, thus utilizing the maximum storage capability of the capacitor and does not experience Zener diode clamp voltage.
