This paper presents a field programmable gate array (FPGA) implementation of a digital circuit that measures in real-time the first harmonic load impedance of medium-frequency (25 kHz-70 kHz) induction heating cooking appliances. The load impedance of a planar inductor coupled to a pan depends on the geometry, pan material, temperature, and frequency. Real-time load measurement is desirable for a...
Multiple-inductor systems are widely present in the current technology. These systems require controlling either the supplied voltage or power to several loads with different requirements simultaneously. As a consequence, the cost and size of the power stage may increase beyond the admissible limits for certain applications. Considering multiple-inductor loads, a novel multiple-output series resonant...
