Hello, here I am!

Only some of you already had a chat with me at Bodo’s WBG event last December. My name is Alfred Vollmer and I’m the new guy in the editorial team of Bodo’s Power, but I am not new to the industry at all; I even wrote a viewpoint like this before: it was for the June 2014 edition of Bodo’s Power as a guest editorial. Like the vast majority of you I am an electrical engineer (German degree: Dipl.-Ing.) which means that I am somewhat tech-savvy in my daily life. You should have seen how proud I was in the early eighties when my first LDO-based “fully stabilized” power supply worked. And I was even prouder after setting up my very first switchmode power supply (SMPS) for a commercial control unit in 1985 that I optimized e. g. in terms of diode costs. But this is old days’ stuff.

Hello, here I am!

Only some of you already had a chat with me at Bodo’s WBG event last December. My name is Alfred Vollmer and I’m the new guy in the editorial team of Bodo’s Power, but I am not new to the industry at all; I even wrote a viewpoint like this before: it was for the June 2014 edition of Bodo’s Power as a guest editorial. Like the vast majority of you I am an electrical engineer (German degree: Dipl.-Ing.) which means that I am somewhat tech-savvy in my daily life. You should have seen how proud I was in the early eighties when my first LDO-based “fully stabilized” power supply worked. And I was even prouder after setting up my very first switchmode power supply (SMPS) for a commercial control unit in 1985 that I optimized e. g. in terms of diode costs. But this is old days’ stuff.

Immediately after graduation in the mid-eighties I started my very first job writing about semiconductors for a German publication. In these days there were only very few power semiconductor applications, and motor control was very different from today’s energy-efficient inverter applications. However, with the advent of more affordable and more attractive power semiconductors I have been able to witness the success and conquest of new power semiconductor generations and technologies. I have always listened from row #1 because, being an electronics journalist for more than 30 years, also meant getting the information first-hand and talking to the experts quite frequently.

Today, wide bandgap (WBG) semiconductors based on Silicon Carbide (SiC) or Gallium Nitride (GaN) are THE hot products in our industry but definitely not the universal remedy for all application hiccups or challenges. SiC and GaN devices are often more expensive when you only look at the pure high-power semiconductor, however, from a system level perspective WBG semiconductors offer many advantages and they even enable some applications that haven’t been economically or technically feasible before. I personally consider this view at the system level design to be one of the most important challenges of design engineers. This is why I will always keep the overall system implications in focus even while writing/reporting about very deep-diving technology and application-oriented details.

Please send me an e-mail to alfred@bodospower.com and tell me what you really want to read about! Bodo’s Power is here to help you to solve your power design problem, and together with Bodo and Holger I will do my very best to serve to you exactly the information you need – promised!

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 our magazine with every single issue is available for free at our website bodospower.com.

My Green Power Tip of the Month:
Unplug AC adaptors when not in use – especially when they still feel warm because their ohmic resistance is too high. Perhaps it is time to get rid of these old chargers, disposing of them properly, even though this creates new electronic waste. The new generation of (fast) USB-C charging devices will help your decision.

Kind regards,
Alfred Vollmer
