| Summary: | In order to increase the application of renewable energy sources in the hybrid electrical vehicle application and also for zero tailpipe emission, a typical DC power converter interface in addition of effective control of power flow is very important. On that aim, a novel four port dc-dc power converter with bidirectional power flow is proposed to integrate the two input ports for photovoltaic (PV) and battery to two output ports for motor load and light load. The MPBC is customized for operating in buck and boost states with power flow control in both directional through changing the switching combinations. This system is implemented in hybrid e-vehicles (HEVs), where different level of dc voltages at battery and motor needs to be connected with the capability of bi-directional flow of power in regenerative action of vehicle to charge the battery. The different states of operation, steady state analysis, control scheme to regulate the power are presented. Power loss analysis is carried out to do proper design with more efficiency. The proposed converter simulation is done using MATLAB/Simulink to verify the validity of design, its behaviors and hardware response in different states of operation. |
