Advanced design and simulation of a hybrid electric vehicle

This thesis illustrates the modeling of power electronics components for a two- mode hybrid electric vehicle. The model designed is for a Texas Tech University Advanced Vehicle Engineering Competition EcoCAR: The Next Challenge. Model of the hybrid electric vehicle is built and simulated in this research. Power electronic components such as the DC – DC converter, Inverter, Rectifier have been built and the power management has been discussed during various modes of operation. These models have been built using PSIM (power simulator) software and the Mathworks tool called the Simpower systems. Models such as the Battery, Bidirectional Buck Boost have been built in PSIM whereas Motor model has been done using the Simpower systems. PSIM tool has been chosen because of the advantage of having most of power electronic components in built. The motor model built in Simpower systems is then tied into the PSIM model with the help of a Simcoupler tool. This Simcoupler tool is a bidirectional tool, hence allowing for the power to flow between the two software tools. The simulation results have been analyzed during the motor mode of operation as well as during the regenerative braking. The battery voltage, Buck Boost Converter Voltage, Inverter output 3 phase current and voltage, motor output Torque and speed are discussed in this thesis.
