Abstract
This Master thesis deals with the analysis, simulation and implementation of serial connected converters. The focus is laid on the design of a single phase equivalent cell, comprised of a standard three phase - two level voltage source inverter connected in series with a bidirectional full bridge converter via a high frequency transformer. In order to realize the high frequency operation of the transformer a modification in the sinusoidal PWM is implemented. Also, several schemes for commutating the bidirectional full bridge are analyzed, simulated and tested. Transformer design aim on the minimization of leakage inductances and for this reason three prototypes are constructed compared.
