Output Voltage Control of a 3-Phase Multilevel Inverter Considering Input Voltage Fluctuations using PI-Technique
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 10
Abstract
A new approach for the control of the superposition ratio of odd harmonic wave into output voltage feedback control and improvement on voltage utilization factor has been presented. The input DC source is considering from cogeneration system, In case of the power generation using natural energy and fuel cell comparatively large fluctuations are generated at the DC voltage. This paper presented detailed analysis of the improvement on the controllability and absorption of the DC voltage fluctuations has been absorbed using SVPWM with PI-control technique. The results have obtained using 3-level inverters with 6kW Resistance load. Results are validated with MATLAB/ simulink.
