In this paper, multi-channel capacitive sensor arrays based on microstrip band-stop filters are studied. The sensor arrays can be used to detect the proximity of objects at different positions and directions. Each capacitive sensing structure in the array is connected to an inductive element to form resonance at different frequencies. The resonances are designed to be isolated in the frequency ...

A novel Z-source three-level inverter based on coupled inductors is proposed. The two inductors in traditional Z-source impedance network are replaced by two coupled inductors. The operating principle is described and the equations of boost factor and voltage stresses are deduced. Comparisons are made with other Z-source three-level inverters, especially the multicell switched inductor Z-source...

This paper proposes a model of coupled inductor which takes into account the influence frequency, temperature, and constant component, IDC, currents in windings on parameters considered element. A description methods measuring using an impedance analyzer chamber for thermal measurements is given. The obtained results are compared with calculations proving satisfactory match.

Four-turn coupled (flux-closed) inductor structures have been fabricated and tested for use in high-power-density integrated voltage regulator (IVR) applications. Our solenoid-like structure is comprised of a laminated magnetic core of four rungs surrounded by four Cu windings creating four coupled inductors. The magnetic core is made of laminations of ultra-high-vacuum-sputtered [5 nm Ta/200 n...

This paper presents an interleaved boost converter with coupled inductors for photovoltaic (PV) energy conversion. The proposed soft-switching boost converter uses an interleaved method to increase its power density and coupled-inductor technology to extend its step-up voltage ratio. To reduce switching losses of active switches, the proposed interleaved boost converter incorporates a synchrono...

Radio frequency (RF) tunable inductors have a major role in current situation where compact designs with high performance are demanded. The capability of the tunable inductors, to tune the inductance with high or proper quality factor (Q-factor), has been a good advantage in the tunable systems to the designers rather than to use the tunable capacitor which exhibit poor reliability and require ...

This paper presents and implements a single-stage high-power-factor light-emitting diode (LED) driver with coupled inductors, suitable for streetlight applications. The presented LED driver integrates an interleaved buck-boost power factor correction (PFC) converter with coupled inductors and a half-bridge-type series-resonant converter cascaded with a full-bridge rectifier into a single-stage ...
