The main principle behind this both AC- and DC-capable, cost-effective current sensing approach, which is on top potentially superior to shunts from the thermal management point of view, is the real-time resistance identification (RTRI) of the Cu-trace in situ through the auxiliary inductive current sensor (ICS) and a band-selective signal processing algorithm. The ICS does not need to have high bandwidth since the temperature-driven resistance drift takes place at low rate and the PWM frequency is typically between 1 and 100 kHz. Still, the resultant composite current sensor can be part of high-speed converters’ current control loop. The feasibility of the method was demonstrated by designing, manufacturing, calibrating, and testing a PCB-based prototype of the sensor system. We excited it with unipolar triangle-like current waveforms having high DC content to emulate the expectable current signals with current ripples. The dynamic current measurement results were verified using a series shunt as a reference. Based on this, the achieved accuracy of our method, for the applied waveforms up to 100 A and beside Cu-temperatures between 17 ◦C and 62 ◦C, was shown to be between 0.93% and 1.10%. For completeness, the expectable Cu-resistance was also determined in parallel, by direct onboard temperature measurement, showing excellent correlation with our algorithm. © 2024 Institute of Electrical and Electronics Engineers Inc..
