Low Noise, High Efficiency DC-DC Converters
Polytron Devices has launched its new TLB5 series of 5 watt DC-DC converters for telecommunications, measurement equipment, industrial control systems and many other applications. The TLB5 power supplies deliver low noise of 10 mVp-p and 89 percent power supply efficiency in one compact, industry-standard DIP package of 1.25 x 0.80 x 0.40”. The TLB5 product […]
45W/65W ~EPS-45S/65S series Power Supply from MEAN WELL
In order to meet the miniaturization and energy saving demands for related end electronic products from the industrial and control market, MEAN WELL is pleased to unveil the 45W/65W ~EPS-45S/65S series with merely 3” x 2” PCB board size after the same 45W/65W EPS-45/65 series (4” x 2”) were released. The features of these two […]
Efficiency in power conversion circuits
by Steve Roberts, Recom A quick review shows the sources of inefficiencies in both linear and switching power supplies. Most engineers know that one reason switch-mode power supplies have become widely used is their high energy efficiency. But many engineers don’t know power supply technology well enough to explain the sources of switch-mode efficiency and […]
Power quality analyzer checks three-phase lines—and doubles as BS detector for false energy efficiency claims
If you want to really see what’s happening on power lines, you need an instrument that can generate a phasor diagram of the line voltages and currents. An instrument able to do that and much more recently became available from Keysight Technologies. Engineers can use the firm’s IntegraVision PA2203A four-channel power analyzer to observe three-phase […]
Smart power for smart systems
by Gerald Hovdestad, Director COTS Engineering, Member of VITA Committee 46.11, 62 & 65, Behlman Electronics The need for smart power sources able to complement smart systems is becoming increasingly important. In the past, system designers would decide on components needed to accomplish a required function or mission. Once all the components were known, the […]
Orion Fans Maximizes Airflow, Minimizes Noise with New 70mm Fan Package
Orion Fans has developed a series of 70mm tubeaxial DC fans that deliver high airflows ranging from 19 CFM up to 60 CFM with low noise levels of 49.5 dB down to 29.0 dB. The new OD70 family of 70mm fans maximize performance in a wide range of enclosure applications. Nine different fan models are […]
Top power electronics threads on EDAboard.com – November
3V – 5V high current 150A power supply – I have been asked to generate a 100A RMS precise sinusoidal current. It will have negligible burden/load. Luckily I’ve done something very similar in the past where I used a LEM sensor, a dsPIC33, and an inductive load and a current-controlled PWM inverter based on a PI […]
240/320W Harsh Environment Power Supply from MEAN WELL
In order to meet the demands for high-grade AC/DC power supply -with low noise and has to operate under highly humid, highly dusty, highly oily, highly salty, ultra low or high temperature, heavily vibrating, high altitude and poor ventilation environment- MEAN WELL is pleased to unveil the 240W/320W ~HEP-240/320 series soon after launching HEP-100/150/185/600 series […]
Single-Chip 15-W Wireless Power Receiver works with Qi v1.2
Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, introduced the industry’s first[1] single-chip wireless power receiver (RX) that can operate at 15 watts (W) and is compliant with Qi™ v1.2, the wireless charging standard. The TC7766WBG triples the received power capability of its predecessors[2] with […]
