Abstract
The current circuit arrangement is used to reduce the switch-on power dissipation of a power transistor which intermittently switches a direct-current voltage to an ohmic-inductive load and in which a voltage limiting diode is arranged parallel to the load. The current circuit arrangement employs a non-linear resistance member in series with the diode which resistance member includes at least one additional diode. In addition,a reactance member is used in parallel to the resistance member. Various one-phase and three-phase invertor stages may use the current arrangement.
