Boost Derived Hybrid Converter for Simultaneous DC and AC Applications using Single DC Source Supply

Abstract: The paper proposes a hybrid converter topology which can supply both dc and ac loads from a solitary dc input. These topologies are derived from boost converter by replacing the controlled switch with a voltage-source-inverter bridge network. The resulting hybrid converter has lesser number of power switches to provide both ac and dc outputs with an increased reliability. And the proposed converter have better power processing density and reliability, which can be well suited for systems with simultaneous both ac and dc loads,The proposed converter in this paper, is called boost-derived hybrid converter (BDHC) as it is derived from the conventional boost converter. A modified PWM control strategy is described for BDHC. Keywords: Hybrid converter, power switches, Voltage Source Inverter, modified PWM.
