Fusion power supply advances by the J-TEXT engineering team

Abstract

In order to meet the stringent requirements of fusion power supply for large-scale fusion devices, the J-TEXT engineering team has carried out key technology research and applications in several important directions of fusion power supply. This article presents the advances made by the J-TEXT engineering team in recent years in the following areas: (1) high-voltage power supply for auxiliary heating system; (2) breakdown protection device for auxiliary heating power supply; (3) magnetic field compatibility; (4) high-voltage pulsed power supply for field reversed configuration; (5) large physics experimental facility control system. The research backgrounds, technical progress, test results, applications, summaries and prospects are described in detail in each part. These innovative research results and valuable engineering experience can promote the progress of fusion power supply technology, and also lay a foundation for the development of power supplies with higher parameters in the future.
