In this regard, emerging applications, such as offshore wind farms, require a high voltage gain dc/dc conversion system to interface with high-power transmission networks. This paper presents a new high-voltage gain resonant switched-capacitor dc/dc converter for high-power offshore wind energy systems. The proposed dc/dc converter is characterized by the resonant switching transitions to achieve minimal switching losses and maximum system efficiency. Therefore, a higher switching frequency is conceivable to attain a higher power density. The double stage output voltage of the proposed converter operates at seven times as high as the input voltage with a small device count. The output capacitors are charged and discharged continuously by a 180◦ phase shift with respect to each other to eliminate the output voltage ripples with the low capacitance requirements. The proposed series-modular and cascade configurations show the intrinsic advantage of being readily applicable to multistage power switching converters. The developed topology has been implemented on a 5-kW prototype converter to test its feasibility.

Offshore 5–10-MW marine turbines are becoming more attractive for the wind power industry. In particular, they increase the efficiency and reduce generation cost, compared to previous wind turbine technologies. The power capacities of these offshore behemoths result in an increase in the size of each component. Therefore, offshore wind turbine manufacturers are attempting to create an optimal design for large marine turbines. The optimized design of offshore wind turbines should cope with the following challenges to make high-power conversion systems a feasible alternative. Bulky and huge electrical components have high investment costs because of the more difficult erection and the equipment transportation from the shore to the installation sites. In addition, there is a greater need for high reliability due to the inherent lack of turbine access at sea, which makes operation and maintenance more difficult. Therefore, an optimal power conversion system should feature high-power density, high efficiency, high reliability, and low costs for high power offshore wind energy applications.

A conventional HVDC system uses an ac line frequency (50/60 Hz) transformer to boost the voltage and ac/dc converters for rectification and power flow control. This technology is robust and reliable, but it causes a considerable increase in weight and volume, which leads to higher installation cost. A high-power density can be obtained by replacing the bulky 50/60-Hz transformers with high-frequency transformers. Unfortunately, high-frequency transformers with large turn ratios are difficult to design at high voltages and mega power levels because of the enormous expense of the magnetic material, core, and dialectic losses. One of the key-enabling components for HVDC is the high power dc/dc conversion system because it has a rigid structure, is easy to control system and more compact

The proposed converter combines the output of two modular cells to reduce the device count, output capacitance requirements, and total capacitor power rating. The principle of a soft- switching operation and output voltage analysis of the proposed converter are described in detail. The output capacitors are charged and discharged continuously by an 180◦ phase shift with respect to each other to eliminate the output voltage ripples without adding extra components. In this paper, the series-modular and cascade RSC configurations are introduced to increase the reliability and reduce the control complexity. These configurations are verified by a simulation and their efficiency, volume, weight, and device count are compared with a counterpart to highlight its advantages for high voltage and high power offshore winds applications. A comprehensive collection of the experiments are carried out to evaluate the feasibility of the proposed converter.

The soft-switching action is provided by the resonant condition of the circuit. Therefore, the switching losses are minimal in both ON and OFF instants, and the power density of the system can be enhanced by increasing the switching frequency. Output filter capacitor voltages are phase shifted by 180◦ with respect to each other to eliminate the output voltage ripples without adding extra components. The proposed series-modular and cascade RSC configurations have the inherent advantage of being readily applicable to multistage power switching converters. Conceptual comparisons of the proposed converter to a counterpart showthat the proposed converter is well suited for high-voltage and high-power offshore wind applications requiring a high-power density and high efficiency. The simulation and experimental results confirm to verify the feasibility of the proposed converter.
