ABSTRACT:
A method and apparatus for isolating and/or eliminating RFI, EMI, and noise transients in power supply circuits. The circuit isolates DC to DC and AC to DC power coupling by use of dual, parallel current paths that are alternately gated. The gating of the switches is controlled by a control module, which ensures that the input and output of the circuit is electromagnetically blocked during any instant in time, while simultaneously ensuring proper and continuous delivery of current to the circuit output load.
