Figure 1: Power stage of the flyback converter (simplified)

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

Using Bidirectional Programmable DC Power Supplies for Battery Testing

Zeke Pietsch, Sr. Applications Support Engineer, EA Elektro-Automatik

In today’s fast-paced world the need to create quicker, more mobile mechanical devices is steadily increasing. One primary method for doing this is to replace traditional gas powered or plugged-in devices with battery power. Batteries have become smaller and increasingly efficient as a result. In order to ke

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

How to Increase High-Power EV Battery Charging using Surface Mount Power Devices

Martin Schulz and Philippe Di Fulvio, Littelfuse, Inc.

End users expect new EV designs to minimize vehicle idle time, especially for long-distance driving. EV automotive designers need to increase charger power output, power density, and efficiency to achieve the fast-charging end-users expect. Single-unit, charger designs currently range from 7 kW to 30 kW. The co

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
