Abstract
Surge protection is provided for a d-c power supply, wherein rectified a-c line voltage is filtered in an LC filter having a shunt-connected filter capacitor, by inserting a limiting resistor in series with the filter capacitor during power-up to reduce the inrush current and the voltage overshoot to acceptable values. Once the power-up period is over and d-c power is fed to a load, the limiting resistor is bypassed.
