  • Circuit arrangement for limiting and regulating the collector current of the control element transistor of a switching network component
    Patent number: 4328537
    Abstract: An integrated regulating module for current and voltage regulation is employed in a circuit arrangement for limiting and regulating the collector current of a control transistor of a switching network component. The module comprises a pulse width modulator, a reference voltage source, an operational amplifier for current regulation, an operational amplifier for voltage regulation, a disconnect device and two dual outputs. The control transistor is connected in series with a current transformer whose secondary is connected in parallel to a series arrangement of a diode and a variable resistor, and a half-wave rectifier circuit. Two bistable switches are provided such that one input of the first bistable switch is connected to the reference voltage source of the regulating module and the other input is connected to the output of the regulating module.
