<p>A circuitry arrangement for elimination or damping of the "surge" effect in electrical circuits. It has a ballast resistance in series (BW1, BW2) in series with the uncontrolled electric valve and relevant load circuit switch in the current carrying half wave from which is used to take over the storage voltage in the first current flow path. The ballast resistor has its value so designed that the value of the 'surge' current is limited to below that of the take off current of the current user at full loading. The ballast resistor is short circuited by a notching device into the following half wave of the storage voltage when the uncontrolled electric valve is in the duct conduction.</p> |
