This paper proposes PV based multiple input bidirectional buck-boost DC-DC power converter to interface more than two DC sources from diverse voltage level. This find application in hybrid electric vehicles. When different sources of DC voltage of unequal voltage level need to be connected with bidirectional power flow capability. The converter can be used to operate in both buck and boost mode with Bidirectional power control. It is also workable on control the energy flow between at whatever two sources at more than two source are actively transferring the energy to possible direction. Boost converter is used to step the PV voltage with low output current ripples. The proportional integral derivative (PID) controller it provide required gate pulses to transistor switches used in bidirectional DC-DC converter. The proposed converter used for HEV application for real-time hardware in the closed loop system.
