  • Switching voltage regulator for switch mode power supply with planar transformer
    Patent number: 6987678
    Abstract: A power supply has an output circuit for a secondary stage of a converter that switches on and off a switching device such that the output voltage of the converter is regulated across a capacitor without use of an inductor in the output circuit. For example, the switching device is a semiconductor field effect transistor controlled by a comparator. The output circuit may be used with a switch mode power supply comprising a coreless, planar isolation transformer.

  • Single wire current sharing control technique for the parallel/redundant operation of a plurality of PWM converters
    Patent number: 6346798
    Abstract: A modular power supply system includes DC—DC converters connected n parallel and functioning in a PWM mode. The modular power supply system controls current sharing among the DC—DC converters using a single wire current sharing control bus that drives in parallel the inputs of all the DC—DC converters. The output of each DC—DC converter is applied to a logic OR circuit. Each converter has an identical logic circuit between its output and the single wire current sharing control bus.
