A fully integrated solar charger controller is presented in this paper. The charger has wide input voltage range about 10V to 28V for the solar-powered panel. The input loop regulation is used here as the MPPT protection. This charger also provides different kinds of battery voltages about 4V to 12V. The controller system uses just one error amplifier and no external compensation components is needed...
In this study, the design, fabrication, and calibration of the piezoresistive stress sensors [1–18] embedded in a TSV (through silicon via) interposer in a 300mm wafer are investigated. The results presented herein should be useful for the development of 3D integration such as measuring the strength of the TSV device and interposer wafers, during and after all the processes such as wafer thinning,...
This paper proposes a novel printable multi-functional passive sensor for remote monitoring. The sensor mainly consists of a series of pairs of transmission lines and sensing resistors whose resistances vary with one physical parameter. A short-duration radio frequency pulse as interrogation signal travels along the transmission line and is partially reflected at each resistor due to impedance mismatch...
A new rotor position sensorless method for switched reluctance motor drive system (SRD) is described in this paper. Rotor position can be considered as a function of phase current and the variation rate of it. Using the phase current obtained by sensors and the current variation the rotor position can be estimated accurately and quickly. A control strategy of SRD without position sensor is researched...
Printed interdigital capacitor (IDC) on paperboard is a promising solution for low-cost sensors in intelligent packaging applications. The currently available analytical models of multi-layered IDCs are targeted to those fabricated by conventional semiconductor process. For this reason, we have adapted two promising models and assessed their accuracies by comparison with experimental data. We modified...
