Easy Integration of Supercapacitor Power Back-up

Ally Winning, European Editor, PSD

One of the major trends over the last two decades is to replace mechanical systems with electronic systems wherever possible. Deploying an electronic system usually has the advantage of offering faster and more accurate responses, while being more reliable due to having no physical wear and te

Extending the Supply Voltage of a 600 V Input, No-Optocoupler Isolated Flyback Controller to 800 V or Higher

Yuchen Yang, Senior Applications Engineer and William Xiong, Applications Engineer, Analog Devices

In traditional isolated high voltage flyback converters, tight regulation is achieved using optocouplers to transfer regulation information from the secondary-side reference circuitry to the primary side. The problem is that optocouplers add significant complexity to isolated designs: there is propagation de

Power Supplies for EV Charging Stations

Ron Stull, Power Product Marketing Engineer, CUI, Inc.

EVs can now achieve similar mileage as gas-powered vehicles, but it still takes more time to charge an EV than to refuel a gas vehicle. Charge time is approximately equal to the amount of energy delivered to the battery divided by the charging power; therefore, it is desirable to use as much power as possible to

Compact Filter Saves Space in Three-Phase Power Applications

Patrik Kalbermatten, Senior Manager - Distribution Promotion, Product Management MSABG - Magnetic, Sensor and Actuator at KEMET, part of the YAGEO Group

EMI-RFI filters are needed to attenuate common-mode and differential-mode EMI (or noise). Although simple in principle, they are not easy to design and often require specialist help. Moreover, in three-phase power applications, adequate filtering can occupy a large volume. An integrated three-phase filter ca
