Boost Derived Hybrid Converter implementation using fuzzy controller

The hybrid converter topology presented in this article is called Boost Derived Hybrid Converter (BDHC), it can supply dc and ac loads simultaneously from a single dc input. This topology is realized by replacing the single control switch of a boost converter with an H-bridge inverter. The presented hybrid converter requires lesser number of switches. DC and AC outputs have high reliability, due to its essential shoot-through operation. Better power density and reliability can be well suited for Nano grids in residential applications. A suitable pulse width modulation (PWM) control strategy is devised for BDHC is described in this paper. The implementation of a fuzzy logic controller using output voltage as feedback for significantly improving the performance of BDHC is proposed in this article. The simulation results shows that dc and ac output voltages can be controlled independently in steady state condition of BDHC.
