Two-Stage Boost Inverter for Wave Energy Conversion
摘要：
减少对化石燃料的依赖正在成为全球大多数国家的主要关切。在此背景下，本文提出了单相两级升压逆变器系统的波能转换。所提出的基于波浪能的功率调节系统包括基于波浪能的功能块、永磁同步发电机、Zeta变换器、单相H桥逆变器和电阻性负载。升压逆变器用于将由波浪能转换器系统使用zeta转换器供电的永磁发电机的电压升压，然后使用H桥逆变器将其逆变。因此，可变幅值的交流电压被转换成恒定频率下的恒定幅值的交流电压。在MATLAB/Simulink平台上对各部件进行了模块化设计，使其在负载端输出1kW的功率，并进行了仿真研究。仿真结果的提出和讨论，以显示如何波供电升压逆变器可以有效地将波能转换为电能和条件的电力之前，它馈送到任何AC负载或AC电网。最后对基于zeta变换器的波浪能转换系统进行了性能分析
英文摘要：
Mitigation of fossil fuel dependency is becoming a major concern in most of the countries around the globe. In that context, this research article presents the single phase two stage boost inverter system for wave energy conversion. The proposed wave energy based power conditioning system includes wave energy based functional block, permanent magnet synchronous generator, zeta converter, single phase H-bridge inverter and a resistive load. The boost inverter is used to boost up the voltage availed from the permanent magnet generator powered by a wave energy converter system using zeta converter and then invert it using an H-bridge inverter. Hence variable magnitude AC voltage is converted to constant magnitude AC voltage at constant frequency. The blocks of each component is designed to deliver the power of 1kW at the load terminals and simulation study is carried out in the MATLAB / Simulink platform for further analysis. The simulation results are presented and discussed to show how wave powered boost inverter can efficiently convert the wave energy to electrical energy and condition the electrical power before feeding it to any AC load or AC grid. The performance analysis of wave energy conversion system based on zeta converter is included at the end of the article
