<p>The invention relates to a changeover discharge circuit for an electronic switching circuit of the type having a semiconductor switching element in series with a DC source and an inductive load. Initiation of the discharge current of a discharge capacitor is delayed upon the switching on of the switching element until the substantial termination of the load current by a commutation choke coil and a recovery diode in shunt with the load.</p> |
