This article deals with a single-phase inverter topology evaluation for a non-axisymmetric in-vessel coil system in a tokamak. An IGBT-based power converter topology is investigated to supply the magnetic system composed of several independent coils. The dc-ac converter topology used for a single coil consists of a single-phase inverter with an interleaved leg and unfolding switching strategy. The converter operation and control investigation are carried out with a Hardware-in-the-Loop (HIL) approach. In the paper, the main control design requests and the issues of this application are explored. Then, the effectiveness of the proposed approach is validated by the HIL.

Abstract

This article deals with a single-phase inverter topology evaluation for a non-axisymmetric in-vessel coil system in a tokamak. An IGBT-based power converter topology is investigated to supply the magnetic system composed of several independent coils. The dc-ac converter topology used for a single coil consists of a single-phase inverter with an interleaved leg and unfolding switching strategy. The converter operation and control investigation are carried out with a Hardware-in-the-Loop (HIL) approach. In the paper, the main control design requests and the issues of this application are explored. Then, the effectiveness of the proposed approach is validated by the HIL. Furthermore, the selection criteria for the power switches are discussed.
