Abstract	A non-dissipative single-sensor measurement principle has previously been proposed as a simple and effective means for providing control variables for feedforward and/or feedback control and also for parameter estimation. This approach can reduce the number of sensors and eliminate the requirement of complex isolated feedback circuitry in many power electronic systems. In this paper, based on the high-frequency small-signal inductor model, the accuracy of the derived inductor voltage from single voltage sensor or single current sensor is addressed. As the voltage difference between the actual and estimated inductor voltage values can be estimated, it is feasible to check if compensation network in single-sensor measurement principle is necessary or not. Practical issues for measurement and calculation of inductor parameters are also included and explained in the paper.
