Abstract

See full text

A discretely constructed MOSFET is switched by a voltage applied between gate terminal and source terminal. The source terminal has a self-inductance in which a fast change of the load current induces a considerable voltage which opposes the applied gate-source bias. This opposing voltage is reduced since the source contact is connected to an auxiliary terminal which is largely magnetically decoupled from the source terminal. A control voltage is applied between gate terminal and auxiliary terminal. When a plurality of MOSFETs are connected in parallel, oscillations in the control circuit can thus be effectively suppressed.
