  • Current-mode magnetic isolator for switching DC-DC converters
    Patent number: 6285234
    Abstract: A signal isolator using magnetic coupling is disclosed. In contrast to the prior art non-isolated voltage summing circuits, the present invention utilizes current summing and magnetic coupling. In addition to providing ground and signal isolation the circuit of the present invention also provides a current-summing node which is always in a high impedance state, thereby allowing ancillary control mechanisms to be easily implemented in the circuit.
