An in-depth exploration of switched-mode power supplies (SMPS), the principles, architecture, converter topologies, and making the right choice for your application.
Understanding power supplies and inrush current New inrush-current-limiting techniques increase the reliability and life expectancy of power supplies BY MICHAEL ALLEN Bear Power Supplies Phelps, NY http://www.bearpwr.com In ac/dc power converters above a few watts, a large inrush current flows ...

Power supplies convert AC power to DC power. Most industrial control is standardized on 24 VDC. Power supplies can be configured for a variety of incoming power. Terminal Blocks Terminal blocks are also used to route power to the devices inside the control panel. Each block has two terminals ...
However, fast switching at high voltages poses its own challenges in AC/DC power supplies and inverters. Designers making the transition from planar to superjunction MOSFETs often have to accommodate EMI, voltage spikes, and noise-related concerns by compromising switching speed. Below we will ...
Power Via MDI TLV Power capabilities of a port, for example, whether a port supports PoE and whether a port supplies or demands power. MED TLVs MED TLVs are related to voice over IP (VoIP) applications and provide functions such as basic configuration, network policy configuration, address ...
AC Test Definitions AC or dynamic tests are typically made with the analog signal at the rated frequency with a signal power of 0.1 dB, 0.5 dB, or 1 dB below full scale (dBFS). If different amplitudes are used, they will be defined in the data sheet test conditions. For these tests,...
Power and Ground Side Switching in Alternating Current Applications Perhaps the terminology of power and ground are most common in DC applications, but the conceptstill applies to AC. Imagine a residential 110 vAC light circuit. Usually, the switch is placed on the ‘hot’ side of the light, ...
Wall Warts, You likely use them everyday without giving them much of a second thought. What exactly goes on inside those chunky black wall chargers that turns AC current into a nice DC trickle for your favorite electronics? Read on to learn more. ...
The deposition rate, measured with a quartz crystal monitor (QCM), was 0.42 Å /sec at 70 W DC power. Electrochemical setup A 900 ml, three-electrode setup with a saturated silver/silver chloride (Ag/AgCl) reference, a 2 cm × 7 cm platinum foil counter electrode, and an...
