Abstract
In many converter applications, the usage of a braking chopper system is required for energy dissipation. Thus, braking chopper solutions need to be found for Modular Multilevel Converters (MMLC). This paper describes braking chopper solutions for the indirect and the direct MMLC. For each converter topology a solution utilizing cells is analyzed. Additionally, taking the direct MMLC as an example, a solution which utilizes thyristors is shown. All chopper solutions have been simulated; this paper shows some of these simulation results.
