Digital control is becoming increasingly relevant in space application of power electronics, offering new opportunities in terms of performance, flexibility, monitoring and system-level optimization, as power converters are required to operate reliably over wide operating ranges and under component tolerances, aging, parameter drifts and changing system configurations.
The tutorial will first introduce the fundamentals of modeling and practical implementation of digitally controlled power converters. Sampling, computation and PWM delays will be discussed together with their impact on achievable bandwidth and dynamic performance. Design approaches based on both equivalent continuous-time models and discrete-time models will be presented.
The tutorial will then address advanced digital-control functionalities, including online identification, controller autotuning and automatic controller reconfiguration. The possibility of embedding stability monitoring functions into power converters will also be discussed, with emphasis on complex power distribution systems containing multiple tightly controlled converters.
Advanced modulation and control techniques for high-performance DC-DC conversion will also be presented. Examples will include optimized modulation of the non-inverting four-switch buck-boost converter and modulation strategies for multilevel flying-capacitor converters. Their potential for improving efficiency, dynamic performance and converter power density will be highlighted. Finally, mixed-signal control approaches combining digital flexibility with high-speed analog functions will be briefly discussed as an attractive alternative solution.

Nuclear technologies are a powerful enabler of current and future space exploration, providing reliable energy in environments where solar power becomes impractical or impossible. From lunar polar regions and planetary surfaces to deep-space missions far from the Sun, nuclear technologies can extend mission duration, increase capability, and unlock new exploration architectures.
The tutorial session, Nuclear Technologies in Space, will provide an introduction to the role of nuclear systems in space exploration, examining why they are needed, the missions they enable, and how their use has evolved over the history of spaceflight. A major focus will be Radioisotope Power Systems (RPS), covering the science of radioactive decay, the criteria used to select suitable radioisotopes, and the design and operation of systems from RTG’s to RHU’s, betavoltaics and more. The tutorial will also explore power conversion technologies, system-level integration considerations, assembly and testing approaches, programme implementation aspects, and a brief overview of ESA's ENDURE programme. The session will conclude with an introduction to nuclear fission technologies for space, including reactor systems, nuclear electric and nuclear thermal propulsion concepts, European activities, and recent international developments.
The keynote session, ESA's Perspectives on Radioisotope Power Sources for Sustainable Exploration, will provide a deeper examination of ESA's ENDURE programme and Europe's ambitions for establishing an end-to-end radioisotope power capability.
