In this paper, the authors propose simulation and comparison of BTB (Back-To-Back) system combining bidirectional isolated DC/DC converters and modular multilevel cascade PWM converters. The system consists of multiple converter cells connected in cascade per phase at both front ends. Each converter cell consists of a bidirectional isolated medium-frequency DC/DC converter and two voltage-source H-bridge (single-phase full-bridge) PWM converters. Extremely low voltage steps bring a significant reduction in harmonics and EMI (ElectroMagnetic Interference) emissions to the BTB system.
