Power Converters are critical components in the performance and the operation of Particle Accelerators. Meetings - scheduled or informally organised - during International Conferences either on Particle Accelerators or Power Electronics are not the best way for exchanging experiences and ideas. POCPA Workshop devoted to the specific field of Power Converters for Particle Accelerators aimed to group specialists in this field from the particle accelerator laboratories worldwide for a two-days meeting and to organise a true round-table on selected topics.
