Title: From Grid Following to Grid Forming Converters Webinar, 2nd April 2026, 5:10 PM (Peru time).

 Abstract Power Electronic converters (PECs) have been in power systems for many decades; however, it is only recently that they have come to account for a significant share of generation, transmission, and demand. PEC has dramatically changed in recent times, from a very limited support role in power system operation to a key element in the transition to a zero-carbon society. The early developments in high-voltage direct current (HVDC) based on Thyristors were a formidable step forward for bulk power transmission. However, the development of more flexible commutation devices and sophisticated control mechanisms, together with appropriate practices and grid codes, is making voltage source converter (VSC)-interfaced technologies a crucial component of modern and future power system operations and paving the way for a secure transition to a zero-carbon society. This short seminar provides a general introduction to power electronic converters and their transition from grid-following to grid-forming, including practical discussions of the importance of several elements and the control philosophy. The seminar includes (but is not limited to) discussing the benefits of a smart grid-friendly converter.

RADIATION TOLERANT POWER ELECTRONICS FOR SPACE APPLICATIONS Doctoral Thesis Jaroslav Laifr Prague, November 2018 

Abstract: The aim of this thesis is to summarize the state-of-the-art satellite electronics design, find its bottlenecks and propose a novel, scientific-based approaches on the space power systems development addressing rapidly evolving so-called "NewSpace" ecosystem. The modern consumer-driven electronics with rising computational power and miniaturization demands similar to the Moore's Law for computers brings new technological challenges and problems. The NewSpace community needs to understand them to successfully conduct its presence in space, both aboard earth-orbiting and interplanetary missions. It is the satellite (manned and unmanned) and aerospace industry, private or government-led institutions which need to follow the technological and scientific progress by faster steps if want to utilize the full potential of the scientific and technological progress in commercially available markets and technological breakthroughs. Initial studies are the follow-up of the author's Master thesis: Fluxgate Magnetometer for Satellite Attitude Control, carried on within the multi-faculty CubeSat project CzechTechSat led by the author as the Principal Investigator. Students were implementing authors' hypotheses within their bachelor and master thesis terms and supported their research and validation. Key findings were implemented as an practical example of the thesis utilization within the Low Voltage Power Supply unit for the Radio and Plasma Waves Investigation instrument selected to be flown aboard the European Space Agency L-Class mission called JUICE (Jupiter Icy Moon Explorer) into the Jovian system in 2023. Also in the project CRREAT by the realization of the ultra low power dosimeter for small satellites. The thesis is also a base of the spacecraft electronics design E-Book called "NewSpace Economically" prepared to be released to the small satellite community in 2019. Keywords: ESA, RPWI, JUICE, CubeSat, NewSpace, Radiation, Power Supply, Satellite.
