Plural commutated-element direct-current current transformer
Abstract:
The present invention provides a plural commutated-element direct-current current transformer (DCCT) that offers wide bandwidth together with freedom from transient disturbances caused by commutation. Plural commutated elements, each comprising a commutating switch and a current transformer each generate, responsive to a commutating signal, a current in a burden, each burden generating in turn a signal representing a DCCT input current. The commutating signal for each element is out of phase with such signals driving other commutated elements. Because of this phase difference, at any given time at least one commutated element is producing a signal free of transient disturbances from commutation. A selector switch, responsive to a selector signal out of phase with all commutating signals, connects to a DCCT output terminal only a burden signal representing the input current that is presently free of transient disturbances.
