Abstract: In recent times, the use of standalone systems with renewable sources to meet individual energy demand is more encouraged by the government due to the following reasons: 1. Green Energy 2. Abundant 3.Fossil fuel depletion and Co2 emission. A new hybrid converter which can simultaneously provide buck, boost and inverted outputs from a single DC source for residential application is introduced in this paper. The proposed converter is a combination of two leg voltage source inverter (VSI) bridge network and a buck circuit, which replaces the switch (S) of a conventional boost converter. PWM control is employed to control the MOSFET switches. The proposed converter topology is simulated in MATLAB and the results are validated with the prototype. The reliability and number of switches employed compares favorably with alternate methods. This converter is capable of supplying AC and 2 DC loads at 110V (rms), 120V and 65V respectively from a DC source of 48V.
Keywords: Voltage Source Inverter (VSI), Pulse Width Modulation (PWM) and Boost Derived Hybrid Converter (BDHC).
