Abstract

A differential voltage probe for providing accurate measurement of differential voltage with high frequency components is disclosed that is further configured to accurately identify noise sources in EMI/EMC applications. The differential voltage probe is configured to provide the benefits of adequate differential voltage measurement bandwidth, galvanic isolation capability, high CMRR, flexible design to accommodate various requirements on voltage rating, loading effect, and frequency range of interest; and/or easy implementation and low cost. The differential voltage probe is able to achieve these optimized capabilities by implementing unique winding designs for transformer(s) used in the differential voltage probe circuit design.
