Heat management technology for solid‐state high voltage and high repetitive pulse generators: Towards better effects and reliability

Abstract

Abstract Solid‐state high voltage high repetitive pulse generators have a broad prospect in various applications. The high power and high‐frequency operation of the pulse generator suffer from the massive heat dissipation problem, which limits the improvement of the output parameters and even affects the lifetime. This article focuses on heat management technology for high voltage high repetitive pulse generators. Firstly, the typical circuit topology of the high repetitive pulse generators was summarised. From the perspective of different application requirements, the demands of the heat management design were concluded. Moreover, the heat generation characteristics and difficulties of solid‐state high voltage high repetitive pulse generators were analysed. Then, the different state‐of‐art cooling techniques were reviewed, and their applicability and limitations for the high voltage high repetitive generators were discussed. Finally, a flow chart for heat management design was given.
