Renewable Energy System with High performance Hybrid Cascaded Inverter
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 1
Abstract
In this paper, Renewal energy system with high performance Hybrid cascaded inverter is proposed. It is based on two kinds of power devices those are MOSFET and IGBT and also the cascaded inverter consists of three H-bridges. The DC voltage of each H-bridge meets the proportional relationship of 1:2:4 and the three modules are connected in series at the AC side. The low voltage bridge is composed of MOSFETs, while the medium and high voltage bridges are composed of IGBTs. This hybrid cascaded inverter can output at most 15 voltage levels at the AC side with rather low switching frequency. At the same time, it can fully exhibit the advantages of different power devices and make the inverter operation flexible. Voltage gradational and PWM carrier modulation methods are adopted in this paper. With different combination of switching states, the distribution of input active power in each H-bridge can be adjusted. As a result, for renewable energy system, larger control freedom is provided and the need of power balance is satisfied. The inverter system is verified with simulation results.
