  • Abstract This thesis proposes a novel N-times voltage multiplier rectifier for high step-up converters which can be used in renewable energy generation systems. This control strategy for the proposed N-times voltage multiplier rectifier circuit is designed based on Time Division Multiplex (TDM) principle. The TDM control strategy can be used to transfer and save energy for the output rectifier diodes and output capacitors at different time intervals. The circuit configuration and TDM control strategy can reduce voltage stress for the output capacitors and output rectifier diodes. Each voltage of output capacitor can almost achieve the purpose of equalizing voltage. The functionality of N-times output voltage can then be realized because of the superposition of the output capacitor voltages. A full-bridge quadrupler converter integrating the proposed rectifier with the specifications of the 48V DC input, 200V DC output, and rated power 150W is designed and implemented in this thesis. Experiments and simulations for the proposed full-bridge quadrupler converter and the conventional full-bridge quadrupler converter are conducted to compare the voltage stress of each circuit component. The results show that the voltage stress of output capacitors in the proposed full-bridge quadrupler converter is less than the voltage stress of output capacitors in the conventional converter. In addition, this thesis also simulates the applications of the proposed N-times voltage multiplier rectifier for high step-up conditions. Simulation results indicate that the proposed N-times voltage multiplier rectifier has great potential to be used in high step-up converters of renewable energy generation systems.
