Non-Intrusive, In-Situ Power Measurement Method

Abstract: a non-intrusive, in-situ power method for measuring the loss associated with magnetic components (for example, an inductor) of a power converter is provided. the method involves first capturing a first set of voltage and current waveforms from the power converter. an additional capacitor is then connected to the power converter and a second set of voltage and current waveforms are captured. based on the first set of waveforms and the second set of waveforms, a timing skew between the current and voltage waveforms captured from the power converter may be determined. this timing skew may then be used to determine the loss of the inductor. the loss may be used to design an optimized power converter.
