Title: Overvoltage protection for D.C. power supply systems - involves R-C circuit connection between power source and distribution fuses to limit transients
Inventor: SCHOTT HEINRICH DIPL ING
IPC: H02H9/00
Filed: 1974-10-30
Abstract: In power supplies feeding voltage sensitive equipment, for example some electronic installations, it is necessary to limit the high voltage transients which can occur when a fuse (Si) interrupts the current due to a fault (K) flowing in the inductive supply leads (L). Such inductively produced voltage may rise to more than ten times the nominal supply value, and can be limited by connecting a high value of capacitance (C1) in series with a diode (D) and resistor (R) parallel combination across the supply between the voltage source and the distribution fuses (Si). The resistor is with advantage proportional such that with maximum charge on the capacitor the discharge current is equal to the minimum current required by the loads.
