Proportional bias switch driver circuit with current transformer
摘要:
A switch bias system is provided that includes a bipolar junction transistor (BJT) switch comprising a base, emitter, and collector; an energy storage circuit coupled to the collector of the BJT, the energy storage circuit supplying current flow to the collector of the BJT; a current transformer circuit coupled to the emitter, the current transformer circuit configured to sense current flow through the emitter of the BJT switch; and a proportional bias circuit configured to generate a bias current to the base of the BJT switch, the bias current set to a proportion of the sensed current flow through the emitter of the BJT switch.
