Abstract

This work shows the hybrid converter topology of boost converter & Inverter, which can supply simultaneous DC and AC outputs from given DC supply. It is shown that by replacing the control switch of boost converter with H-bridge inverter. A new topology is formed which has similar performance to Z source inverter. The resulting converter requires lesser number of switches to provide simultaneous DC & AC outputs while maintaining reliability due to inherent shoot-through protection. A suitable pulse width modulation based on unipolar sine PWM is employed to control switches. The simulation is carried out using matlab/simulink and the results are compared for a better result.
