Safety PLCs (Programmable Logic Controllers) are commonly a part of the Safety Related Control System (SRCS), especially in industrial applications. In most cases, the controlled devices cannot be connected directly to the safety ...

Two different approaches for the calculation of the household photovoltaic (PV) installations energy balance are presented and discussed in this paper. The main methodology is based on the Monte Carlo method is proposed and applied to the case study with the&#x...

Designing alarms for medical equipment may seem easy, but the standards’ requirements combined with the nonlinearity of the acoustic transducers, with the difficulties of assessing the acoustic impedance of the transducer chamber, and w...

Chaotic tags and sensors can be conveniently made using simple chaotic circuits of reduced complexity that can compete with tags and sensors based on a combination of capacitance-, inductance-, or resistance-to-voltage converters and&#...

In this paper, we investigate a non-invasive procedure for static and dynamic modeling of cardiac output and oxygen consumption in response to cardiopulmonary e...

Current collapse in gallium nitridebased transistors limittheir use in high powerand high frequencyconverters. In some cases, it makes the conduction losses to double. This paper investigates the...

Single-phase ground faults are the most common faults in medium-voltage distribution grids. High-impedance grid grounding using a special four-leg transformer is discussed in the paper. The transformer’s zero-sequence impedance differs from positive-sequence impedance&#x...

DC-DC converters control the power flow and thusthe power distribution between the components on differentvoltage levels. They are essential for (dis)charging batteriesand influence the safety and stability of the entire...

Active Gate Drivers have gained of interest asthey allow one to shape the switching waveforms finely,thus reducing overshoots and oscillations. However, whenfast power switches are exploited, the tuning of such driversis still challenging.&#...

One of the basic features of a safety function is the safety integrity level. This feature also affects the technical solution of the system that implements the safety function. One of the parameters that affect the safety integrity of a ...

The paper devotes to a developed wearable photoplethysmographic (PPG) sensor for human heart pulse monitoring. The sensor can work in a weak magnetic field with radiofrequency (RF) disturbance present during patient examination i...

The paper describes the symmetrization method of power converter used in topology of AC traction substation with power balancer. This topology provides the three-phase current symmetrization and the reactive power compensation for AC traction substation fe...

n the paper, we share our research results and experiences with the redundant virtual sensors. The main focus is paid on the creation of the model for redundant virtual sensors, applying the concept of “digital twins” &#x...

n this work we presented the results of the experiment in which a reference signal was used for determining degradation level of cable insulation. A set of reference signals was constructed using programing language. Onwards, each&#...

Main focus of this work is to design a three–phase rectifier based on silicon–carbide power diodes. Main part of the article is dedicated do equations which are then used to obtain temperatures of power diode junction based on current, voltage and switching frequency. From the...

A vestibular schwannoma is a benign tumor,developing in the inner ear. As it grows, it may affectpatient’s hearing and body balance. If not treated, itcan also lead to death of the patient. Once it becomes aproblem...

Teaching microcontrollers at university during face to face activities implies using development boards such as those from Texas Instruments or Microchip. Changing to online teaching due to the coronavirus pandemic needs free simulators to be used by students to achieve&#...
