Abstract

Pulse step modulator (PSM) topology is applied to the EAST auxiliary heating system, which consists of a neutral beam injection (NBI) and the related microwave heating system. This paper firstly analyzes the merits and demerits of the traditional PSM modules adopted by other international companies, and then optimizes the topology of the module using the analysis results. Finally, a new topology for the PSM module (a three-phase neutral-point diode-clamped rectifier) is proposed. This new module overcomes the problems of traditional modules and has better cost-effective performance. The experimental results verify that the new module is feasible for engineering applications.
