Keys to develop high voltage industrial power supplies
 | Join the free online seminar series co-hosted by ST and Würth Elektronik to learn how to design a very high voltage power supply for industrial markets. |
Several industrial applications require an input voltage that exceeds the standard 230 VAC. Typical use cases include systems connected to 3-phase mains voltage, where the control electronics are supplied by a phase-to-phase voltage, as well as industrial motors, online UPS or solar inverters where the auxiliary power supply is connected to a very high voltage DC voltage bus.
The performance and robustness of auxiliary power supplies can sometimes be impaired by the high input voltage required to run the application. In this online seminar series, we show you how to ensure that auxiliary power supplies are robust and power-efficient enough to deal with high input voltages.
Who should attend?
Designers who want to develop their own auxiliary power supply for industrial systems requiring up to 440VAC or 600VDC.
Benefits you will take away
- Learn how to select the best semiconductor and passive components to design a robust very high voltage power supply.
- Identify what contributes to power losses in your supply, in order to optimize its efficiency.
- Practical examples with real measurements carried out on a very high voltage auxiliary power supply.

 | Jiri Smutka, Senior Application Engineer at ST Jiri was awarded a Master's degree from the Faculty of Electrical Engineering of the Czech Technical University in 1996 and now has 20 years’ experience in SMPS design. He has been working for STMicroelectronics Application Center in Prague for 16 years. Besides providing technical support to European customers in SMPS design, Jiri participates in the development of reference designs with ST products and works with marketing teams and Product Groups to create new products. |
 | Giuseppe Ballarin, Senior Field Application Engineer at Würth Elektronik Giuseppe was awarded a Bachelor’s and a Master’s degree in Electronic Engineering from the University of Padova. He started working at STMicroelectronics in 2010 as a Technology R&D Engineer in the Smart Power Division, where he designed, developed and tested ESD protections on silicon. During this period, he also published international papers and documents on this topic. Giuseppe has been a Field Application Engineers at Würth Elektronik since 2016. He focuses on the design of magnetic based circuitry, EMC compatibility and overvoltage protection. He also provides support during EMC tests and delivers seminars focused on electronic design and electromagnetic interferences. |
