Editorial
 WBG at its Best

As engineers, we strive for better solutions to reduce loss in systems to keep up with our environment. Our Wide Band Gap event has become a tradition for engineers that are ready for technical progress. The first week of December at the Hilton Hotel, Munich Airport is the place to be: Bodo’s WBG Event 2026. www.bodoswbg.com. My team and I are looking forward to meeting you again and I am also looking forward to the many great conversations with the experts presenting. The technical program will help you with your designs and the extra long coffee breaks will be good for networking. SiC and GaN have become a mainstream in power electronics teaching us new levels of efficiency in system design.

Celebrating Thanksgiving soon should bring our leaders to end the war so that all the people in our world can have peace.

My words of two years ago are still valid today: It is a pity that diplomacy could not prevent this, as history has shown us there will only be losers left at the end. The people pushing war and terrorism must be stopped. ‘Please stop the War’ is my message to all politicians throughout the world and stand up and work for peace. Do not start more wars.

War continues to destroy the future of people and we already face enough man-made disasters with climate change. All around the world heavy rain causes flooding. So, it is another tough challenge to bring war to an end. There are too many places on earth on fire!

It is tough to see so much aggression day after day on the TV. At some point we also need to overcome religion driven aggression. Educating kids all around the world is the way to Democracy that will result in Freedom and Peace.

All these memories and past stories about war, which were told to me by my parents, return while watching the news on TV. Must the new generation fail and generate the same bad mistakes that history taught us?

Fortunately, our generation has mostly grown up during the last seven decades in peace, but I personally have missed Grandpas and Uncles because they served in the military and did not return home from World War I and II. To see my grandchildren growing up to be called to serve in the military just to defend our country against aggressors makes me sad. Wars definitely destroy the resources needed to save our environment. We need to stop global warming too. Allocating electronic manufacturing resources to defense projects weakens our fight against global warming, with all of the bad side effects. We are all losers in the end, but mainly it will be the wider population who will suffer the most. It will have an impact on all of us. My hope is that all of our children and grandchildren will grow up in peace and that war will not escalate in all areas and set the world on fire. Working to stop the war must be our most important task. There are never winners after wars.

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 bodospowerchina.com. An archive of my magazine with every single issue is available for free at my website bodospower.com.

My Green Power Tip for the Month:
Give print outs a second chance. Turn them upside down and use the paper for your hand-written notes on your desk. I have been doing this for a long time.

Kind Regards,
Bodo
