ABSTRACT:
A high-reactance transformer is used in combination with a phase-programmed switch to limit and regulate the surge current loading on an AC power source employed to charge a capacitor energy store. A controller commands the phase-programmed switch, which begins the charging cycle by closing at a predetermined phase relation to the AC source. The same switch is used to interrupt the charging when the desired capacitive energy store voltage is reached.
