Abstract

This paper focuses on the controller design based on symmetrical optimum and extended symmetrical optimum methods for a single-phase AC/DC converter system employing AC/AC direct converter and inverter with a medium frequency isolating transformer. Design criteria for the control system involve DC voltage control, reactive current control and AC current tracking. Simulation studies verify the designed controller performance for multi-level converter system
