(H)EV traction inverter - hybrid / electric vehicle

An electric vehicle EV is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery , solar panels , fuel cells or an electric generator to convert fuel to electricity. EVs first came into existence in the midth century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. Modern internal combustion engines have been the dominant propulsion method for motor vehicles for almost years, but electric power has remained commonplace in other vehicle types, such as trains and smaller vehicles of all types. Commonly, the term EV is used to refer to an electric car.

Brushless DC motor has simple structure, great power density, torque output and high efficiency. It has a broad application prospect for electric vehicle. The conventional scheme of BLDCM drive system adopts motor ontology, power drive circuits and position sensor. Due to its structure and commutation strategy, it has many problems to be solved if works on electric vehicle. The basic operating principle of Brushless DC motor and the basic power drive system was discussed.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. There are two main groups of electrical motors: DC and AC motors. Electric motor control Application Note 3 V1. However, they are still pretty expensive. Set alert. James F.

To meet HEV's fast torque response, vector control algorithm based on rotor flux-oriented and simulation model is concerned and modular designs for controller's hardware and software are presented in the paper in order to build a platform to achieve the vector control of asynchronous induction motor. Analyze the controller's electromagnetic compatibility, introduce the corresponding antijamming measures to assure the normal operation of the electromagnetic sensitive devices such as CAN bus; experiment proves that the measure is practical and feasible. On the basis of the control logic correct, such as improving CAN bus communication reliability, assuring power-on sequence and fault treatment, carry on the motor bench experiment, test its static properties, and adjust the controller parameters.

Within an electric drivetrain, the inverter controls the electric motor. This is a key component in the car as, similar to the Engine Management System EMS of combustion vehicles, it determines driving behavior. Regardless of whether the motor is synchronous, asynchronous or brushless DC, the inverter always functions in a similar way and is controlled by an integrated PCB, which should be designed to minimize switching losses and maximize thermal efficiency. Not only does the inverter drive the electric motor, it also captures energy released through regenerative breaking and feeds this back to the battery. As a result, the range of the vehicle is directly related to the efficiency of the traction inverter.
