摘要

The renewable energy sources are gaining increasing impetus across the globe because of ever increasing demand for electric energy along with the growing environmental concerns and limited fossil fuel resources. The output voltage of these renewable energy sources has a variable range. In these situations, an additional DC-DC boost converter or step-up transformer is usually needed. The Z-source inverter (ZSI) is an emerging topology for power electronics converters with very interesting properties such as buck boost characteristics and single stage conversion. In this work, the performance of four control techniques of Z-source inverter namely, simple boost control, maximum boost control, maximum constant boost control & third harmonic injected maximum constant boost control with induction furnace load, are compared The simulation results based on MATLAB/Simulink are presented to illustrate the performance comparison of control techniques of ZSI for reducing the harmonic distortion in the load current with induction furnace load in the distribution network.
