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

PFC is Critical to Achieving Energy Efficiency Goals

Joel Turchi, Member of Technical Staff, ON Semiconductor

Almost everyone is aware of the need for optimal efficiency, from consumers and business operators seeking to constrain costs in times of high energy prices, through to designers looking to meet the requirements of an increasingly complex and numerous set of standards. If not already motivated by the high cost of

Figure 1: Rapid switching transitions cause interference

Minimizing Emissions of a SEPIC Converter

Frederik Dostal, Analog Devices, Inc.

Every switch-mode regulator for voltage conversion causes interference. These are partly line-bound at the input side and output side of the voltage converter, but partially these are also radiated. Those interferences are mainly caused by the rapid switching edges. They are only a few nanoseconds long in modern sw

Boosting Operational Efficiency and Predictive Maintenance

Robin Kallsen, Marketing Content Specialist, Omron

Flexibility is the defining factor of today’s manufacturing world. How can companies build exactly what consumers are looking for – and change course immediately in response to changing consumer needs – without sacrificing throughput and quality? Despite the obvious benefits, flexibility can hamper th
