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

The Power and Evolution of GaN - Part 1

Alex Lidow, CEO and Co-founder of EPC

Gallium nitride(GaN)-on-silicon low voltage power devices have enabled many new applications since commercial availability began in 2010. New markets, such as light detection and ranging (LiDAR), envelope tracking, and wireless power, emerged due to the superior switching speed of GaN. These new applications ha

Comm Equip Makers Demand High Power Output & Small Footprint

Tony Armstrong Marketing Director, Power Products Analog Devices, Inc.

Many communications systems are powered via a 48V backplane. This voltage is normally stepped down to a lower intermediate bus voltage, typically to either 12V, 5V or even lower, in order to power the racks of boards within the system. However, most of the sub-circuits or ICs on these boards are required to op

Forward Error Correction (FEC) – Implementation and Test

Andy Cole, Anritsu EMEA

In modern communication systems, information is digitised, coded to logic levels “1” and “0” and often further encoded into complex modulation schemes such as Pulse Amplitude Modulation (PAM) or Quadrature Amplitude Modulation (QAM). Integrity of the information at the received end can be critical, so

How to Easily Test a DC-DC Converter

Alessandro Sanasi, Distribution Field Engineer, Keysight Technologies Inc.

The power system technologies of modern electronic equipment are facing extreme challenges due to the need for an increase in the power efficiency of the systems, especially devices powered by a battery. The main system block involved in power conversion and delivery is the DC-DC converter, which converts DC po

Considerations When Selecting a Power Supply for Test Equipment

Lorenzo Cividino – Director Global Applications & Support, SL Power

When choosing a power supply, if an engineer had only to consider volts and amps, cooling requirements, size, and regulatory certifications, their job would be easy as there are many available options from which to choose. However, designers of test and measurement equipment must consider other important parameters. El

End of an Era for Silicone Transformer Fluids?

Barry Menzies, Managing Director Global, MIDEL

Silicone oil has been used to cool transformers since PCBs were found to be harmful to humans and the environment, but are there better alternatives now? Glancing back to the 1970s, those of us in the power sector can remember when Polychlorinated Biphenyls (PCBs)were the cooling liquid of choice for trans
