Abstract

This research thesis presents analysis and design of a novel Medium Voltage (MV) AC-DC converter topology for wind energy systems. The parallel configuration and phase shifting principles of the proposed converter architecture is suggested to solve the engineering challenges of future medium voltage AC-DC power conversion for wind energy systems, particularly in the power range of 10 – 20 MW. Moreover, to obtain a low complexity design without current mode controller, the role of Discontinuous Conduction Mode (DCM) is performed. As a result, the input and output ripple currents are dramatically reduced. Consequently, smaller input inductance and capacitance filters are also achieved. The input and output ripple current stresses are analysed using PSPICE simulations. The performance of the proposed MV AC-DC converter is compared with the conventional converter in terms of the input and output current ripple stresses and the power factor correction. Simulation results demonstrate that the input ripple currents are only around 11 % compared to the conventional converter. On the other side, the output ripple current stresses of the proposed converter are only 32.5 % of the conventional converter. For that reason, high-efficiency, high-reliability and light-weight MV AC-DC converter for today’s and future wind energysystem can be realized.
