Increasing energy demand and environment constraint of fossil fuels renewable energy is
encouraged. Considering increase in energy demand bidirectional converter is widely used.
the study aims to design and implement a Half bridge non isolated bidirectional DC to DC
converter using fuzzy logic. In the presence of dc mains the converter operates as buck
converter and charges the battery. When the dc mains fail, the converter operates as boost
converter and the battery feeds the load. In both the modes the power switches are controlled
by PWM technique and the PWM pulses are generated by application of fuzzy logic
controller. The proposed converter with controller is implemented and simulated in MATLAB
and the design is validated.
