“…Our aim was to target power metering application domain, where utilization of such system could be beneficial for more users. Such different attempts were already examined; for example, in [6][7][8][9][10], various wireless indoor power data acquisition systems were described. Several approaches and implementation schemes were utilized; however all mentioned solutions were implemented only as a specific application.…”

Data acquisition and processing are well known for some time. Many applications use powerful hardware to acquire, process, and visualize signal waveforms. But there are some applications that do not have to perform high resolution signal acquisition and process large amount of data, for example, low frequency applications of embedded design and applications for remote power grid monitoring. The paper describes special system for low frequency signal data sample acquisition, processing, and visualization implemented as a service on Android-based smart device. The service makes smart device functioning as an oscilloscope or arbitrary waveform generator which is accessible remotely through Bluetooth. The design respects low power consumption requirements, simplicity, and user friendliness in application design. Application scenario was implemented as wireless data acquisition system for power grid monitoring.

“…This is largely due to the increased power requirements of always-on sensor nodes. This creates a need for AC/DC conversion solutions with the output power requirement of below 1 W [1]. Currently available commercial solutions are typically designed with higher output power ranges in mind, and are thus not suited for operation in that power range, since typically suffering from poor power efficiency.…”

This paper deals with the development and experimental verification of a low-power AC/DC converter. The proposed solution is aimed at the sub 0.5 W output power domain, commonly encountered in applications such as always-on wireless sensing nodes. To implement the proposed converter topology, a prototype application specific integrated circuit was designed and manufactured in a high voltage 0.35 µm CMOS technology, able to handle the maximum voltage of up to 120 V. The proposed design was first analyzed by transistor-level simulations showing high power efficiency and low no-load consumption of the developed converter. To facilitate experimental verification and measurement, an printed circuit board with the necessary external components was developed, as the available technology is unable to handle the AC line voltage directly. While the developed converter operated well with decreased input AC voltage, reliability issues arose during operation with the full AC line voltage of 230 Vrms. These are linked to digital control circuitry of the implemented chip and could be addressed in the second manufacturing run in the future.
