  • EU-10099G Rev A

  • EUG-7-100990000
  Description

  • Most regulator circuits used in Dynapower power supplies require current feedback signal from a 50 mv shunt and a higher level voltage feedback signal from the output bus.

  • Also interfaced to the regulator circuits may be signals from external equipment.  The regulators and external equipment are thus connected directly to one of the power supply output busses.

  • It is advantageous to isolate the power supply output bus from the electronic regulating and monitoring circuits.  To this end, the Dual Feedback Isolator Circuit may be used.  The circuit has large bandwidth, excellent linearity and stability, making it suitable for closed loop applications.

  • The circuit has two inputs which are isolated from each other. One channel is used as the current feedback channel and the other is used as the voltage feedback channel.
