  • Patent number: 4720758
    Abstract: A load-dependent current limiter for the power supply of a multi-module electronic system has a programming resistor in each module connected between the power supply voltage and a reference bus. The current through each programming resistor is proportional to the current requirements of the module. The voltage of the reference bus, which is proportional to the total current through all the programming resistors, is compared to the voltage developed across a sensing resistor by the total power supply current. When the sense voltage exceeds the reference voltage, indicative of tapping excess power, a signal is sent from the comparator to shutdown the power supply.

  • Patent number: 4580112
    Abstract: A line filter for a power supply includes a differential amplifier which is driven from across an inductor in series with a principal current carrying path of the power supply. The differential amplifier output is connected to a capacitance returned to ground for canceling common mode interference as may be generated in the power supply.
