Design and simulation of Multi-Input Converter for Renewable energy sources

Abstract

The energy inputs from variety of renewable resources (hybrid systems) requires efficient power converter interface towards integrated management of power load. This study reports a novel power conditioner topology that integrates a variety of renewable energy sources. This allows for higher reliability than what could be attained by a single power source while maximizing the utilization of each source's operational capabilities. It is shown a novel three-input DC/DC converter for hybrid PV/Battery/UC applications. Six power switches are used in the designed converter. Additionally, switching modulation is in no way constrained. By adjusting the duty ratios of the switches, it is possible to manage the battery power, set the UC power, calibrate the output voltage, and monitor the maximum power of the PV source. The input power sources have the ability to supply the load either simultaneously or sequentially while simultaneously charging or discharging the battery.
