Abstract
A voltage doubling circuit including a silicon controlled rectifier (SCR) having a control circuit configured to charge a charging capacitor during a negative alternating current cycle, and including a storage capacitor that receives a voltage from the charging capacitor during a positive alternating current cycle, and by charging the storage capacitor from the charging capacitor when the SCR is off, the storage capacitor is prevented from exceeding its regulated voltage even if the SCR fails.
