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

Power is Vital to Long-Term Space Exploration

Patrick Le Fèvre, PRBX, Chief Marketing and Communication Officer

Visiting the moon, Mars and who knows where next, is far from being an easy job as sustaining life in such hostile environments is much more than just ‘a challenge’. How would we feed the space explorers when they are so far from Earth? In the case of Mars, it would take 210 days for a re-supply rocket to
