SYSTEM FOR TRANSMITTING INFORMATION BETWEEN CIRCUITS

摘要

A system for transferring information from a first circuit to a second circuit includes first and second isolation elements coupled between the first circuit and the second circuit. A first transient filter is located on the second circuit and coupled to the first isolation element. A second transient filter is located on the second circuit and coupled to the second isolation element. A first ground is located on the first circuit, and a second ground is located on the second circuit. The first ground electrically floats relative to the second ground.

1. A system for transferring information from a first circuit to a second circuit, the system comprising:
a first isolation element coupled between the first circuit and the second circuit, the first isolation element for electrically isolating the first circuit from the second circuit and for passing AC signals between the first circuit and the second circuit; a second isolation element coupled between the first circuit and the second circuit, the second isolation element for electrically isolating the first circuit from the second circuit and for passing AC signals between the first circuit and the second circuit; a first transient filter located on the second circuit and coupled to the first isolation element, the first transient filter for passing signals from the first isolation element and for attenuating at least one frequency associated with a transient; a second transient filter located on the second circuit and coupled to the second isolation element, the second transient filter for passing signals from the second isolation element and for attenuating at least one frequency associated with a transient; a first ground located on the first circuit; and a second ground located on the second circuit, wherein the first ground electrically floats relative to the second ground.
