 The Power of Many

As you all know, Wide Bandgap is one of our main focuses. We do a lot to promote this technology, with events, such as Bodo's Expert Talk and by covering it as much as possible in the magazine. Without losing sight of the other topics in power electronics, of course. With all the insights and updates that we receive, it is only natural that I have gained a personal perspective, over the past few years. And while I don't think that SiC competes with GaN, or high with low power, I do feel sometimes that applications like renewables, industrial or mobility, which are obviously on the silicon carbide team, may have a bigger overall impact than low power applications for which GaN is suitable. But maybe I should consider it from a different angle though: Since there is an invasion of smartphones, tablets and other "distractibles", the efficiency gains that gallium nitride can bring while charging and powering these billions of devices cannot be ignored. And these are just a few unnecessary examples, of course there are a lot of important things like servers, tools, e-bikes, motor drives, class d audio and many more. It's like my arguments with my wife discussing whether the automatic motor turn-off in our combustion engine car really is useful or not. Of course, it only saves a tiny amount of fuel and thus CO2 from our car, but it is still a very powerful tool when used by many! With this in mind, it is clear to me that both technologies are equally important and both will play their part in achieving greater efficiency in electronics.

Time is running out and some of the annual events will be here soon, such as the APEC conference and exhibition in March. We all know about the struggles Covid has brought us over the last few years, but it seems we are returning more and more to a continuous schedule of live events. Time to highlight again a popular feature in our March issue, namely the APEC show floor plan within the magazine. The original idea was to print the map in the centerfold of the magazine allowing it to be easily be taken out and used to navigate around the fairgrounds. And of course, to also to find Bodo's partners, as all their logos will appear on this page. We don't have data on how often this tool has actually been used, but what I do know is that it has become very beneficial and admirable to be included on this map. And what can I say, there is still a chance that your logo will appear on the APEC floor plan, even if you are not yet our partner. If you are exhibiting in Orlando and are interested, contact us at to find out how to be included.

Bodo’s magazine is delivered by postal service to all places in the world. It is the only magazine that spreads technical information on power electronics globally. We have EETech as a partner serving our clients in North America. If you speak the language, or just want to have a look, don’t miss our Chinese version at An archive of the magazine with every single issue is available for free at our website

My Green Power Tip for the Month:
Choose the right technology when you purchase new electrical devices. State-of-the-art technology always compensates for its higher cost through higher efficiency savings over time. The cheapest device is not always the most economical.
