Abstract
Due to the increase in the use of renewable energy, there has been a rise in the number of research related to smart or Hybrid converters. So, this work presents the characteristics of a Hybrid converter according to load fluctuation.‘Load fluctuation’, referring to instability from a fast-changing load or instability from an input source to the converter. The experiment will help to determine the sensitivity of devices suitable for connection to the converter. The aim was achieved through experimentation on a 5kW capacity Hybrid converter with an efficiency of over 90% for both AC and DC input sources. Real-life experimented results suggest that the converter is capable of fast stabilization of instability or fast fluctuation from either the load or an input source.
