Esai source code pure electric vehicle motor drive and vehicle control system based on DSP and bidirectional Z-source inverter

The Z-source inverter is a new topology proposed in 2003. It can adapt to a wide range of DC input voltages and is therefore very suitable for use in electric vehicle motor drive systems. This project applies the bidirectional Z-source inverter to the motor drive system of pure electric vehicles. Using TMS320F2808 DSP as the control core, the SVPWM control technology based on the Z-source inverter is implemented. At the same time, the induction motor control algorithm based on the Z-source inverter is implemented through high-performance DSP, which can stabilize the DC bus voltage at low speeds and solve the problem of poor power performance caused by the voltage drop of the power battery; at high speeds, through Increasing the bus voltage improves the power performance of electric vehicles at high speeds. It has strong engineering practical value and is especially suitable for motor applications that require wide speed regulation and frequent changes in torque and power.
