 Continuity Counts

The second pandemic year will end soon, and we hope you have the opportunity to end the year in a contemplative way and with your loved ones. Unfortunately, Covid still dominates many areas of our lives, and this will continue for some time. In such times it is even more important to experience continuity! Even if it is only in the form of a monthly magazine discussing power electronics. We would like to take this opportunity to thank all of our partners who made it possible for us to deliver the magazine on time, every month throughout 2021. And we are deeply grateful and happy to say that this will continue during 2022. This is not always straightforward in these times when raw material is becoming permanently more expensive and postal providers are raising prices almost arbitrarily as they please!

At the end of the year, it is important to rest and remember the friends who are no longer with us. To represent all those we have lost, let us name the following two colleagues: Dr. Artur Seibt died in early 2021. He contributed a number of articles over the years, and Bodo and Artur had a great friendship going back to Bodo’s days working for Harris. Dr. Ray Ridley informed us that Sanjaya Maniktala, a respected expert in the area of power conversion, passed in February. Let us all take a few minutes to rest and remember those who have crossed our paths in the past. We must face the fact that we are all getting older and so are our friends in industry. It is good to see young engineers filling the positions and helping to show continuity!

As in the past couple of years, we will make a donation, instead of sending gifts and cards for Christmas. The postal service has become very expensive and the feedback we received motivates us to continue this tradition. We have chosen UNICEF again; as it is a global organization that fights for the rights and wellbeing of children. We are sure, that this is a worthy investment.
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 in North America. If you are using any kind of tablet or smart phone, you will find all our content on the website If you speak the language, or just want to have a look, don’t miss our Chinese version:

My Green Power Tip for the Month:
We all love the festive lights in our homes at Christmas. Nevertheless, we should act with a sense of proportion. How much does it really need? Less is often more!

Kind regards
Bodo and Holger
