  • Apparatus and method for isolating a field power source and a control power source in a controlled process
    Patent number: 6759767
    Abstract: An industrial control output device is provided which provides electrical isolation between device power and field power. The device includes two isolation devices, one of which is adapted to energize a power switching device, and the other is adapted to de-energize the switching device. The output device thus minimizes or reduces EMI/RFI emissions and provides fast switching times in selectively providing power to a load. In addition, the invention includes a method of providing power to a load in an industrial control system, which allows fast switching of a digital output with minimal or reduced EMI/RFI emissions.

  • Single drive transformer with regenerative winding for p.w.m. supply having alternately conducting power devices
    Patent number: 4493017
    Abstract: A drive transformer for use in a p.w.m. power supply which has alternately conducting power switching devices. The single transformer includes a primary winding, a secondary winding and a regenerative winding. When one of the devices finally becomes nonconductive the other of the devices may turnon. The regenerative winding aids the conduction of that device and also reinforces the drive signal to the device which receives from the drive circuitry of the supply a turnon drive signal.
