A Versatile ± 25-A Shunt-Based Current Sensor With ± 0.25% Gain Error From − 40 ∘ C to 85 ∘ C

This article presents a versatile shunt-based current sensor for battery management applications. It digitizes the current-induced voltage drop across an external shunt resistor with the help of a 2 nd -order delta-sigma ( ΔΣ ) ADC, whose summing node is implemented as a low-noise capacitively coupled amplifier. To compensate for the shunt’s...

Temperature-sensing performance of polymer-derived SiAlCN ceramics up to 1000 °C

Temperature sensors that can operate in high-temperature and harsh environments are highly desired. However, this is a great challenge for sensing materials to operate under extreme working conditions because of oxidation and/or corrosion at high temperature. In this study, polymer-derived SiAlCN ceramics were prepared as sensing materials to...

Reducing Measurement Uncertainty of Temperature Coefficients of Photovoltaic Modules

In temperature coefficient measurements of PV modules, a low level of agreement in results is observed between different laboratories, with deviations up to ±10% for Pmax temperature coefficients. Such deviations are considered as an uncertainty component in PV energy yield assessments, and are seen as financial risk by investors and purchasers....

Effect of particle contact on the electrical performance of NTC-epoxy composite thermistors

As demand rises for flexible electronics, traditionally prepared sintered ceramic sensors must be transformed into fully new sensor materials that can bend and flex in use and integration. Negative temperature coefficient of resistance (NTC) ceramic thermistors are preferred temperature sensors for their high accuracy and excellent stability,...

The Need for a New Parameter on PV Modules Datasheet: Shading Tolerability

This paper suggests a measurable parameter, the so-called Shading Tolerability (ST), to be added on PV modules datasheet. Using this parameter, PV modules can be compared and classified regarding the ability to oppose shading effects. The parameter is extracted based on mathematical and probability analysis, then measured using a Large Area...
