To properly control an inverter, a modulation technique is needed. Many different approaches could be done to control it. Nevertheless, some parameters such as DC-link voltage utilization, produced harmonics and the final implementation with a DSP (Digital Signal Processor), should be considered before choosing which one is the most suitable for any project.
When we want to obtain a specific velocity in our motor, we need to tune the parameters of our controllers to ensure the stability and fast response of our motor, as it will be the main power for the EV. Having this, the security and reliability of our vehicle will depend directly on How good we are tuning these parameters. Here we will explain how to tune them.
A PMSM Dynamic Model needs to be done and implemented if we want to simulate and work with our drive system. For that reason, we will explain all the maths behind the theoretical model of the Simulink/Matlab solution.
To start making a Drive System, we need to have a piece of good knowledge of the dq frame in order to operate with the motor. In addition, we need to choose the control method. Let's start!
Nowadays, due to a lack of fossil fuels, the electrification of the drivetrains will be the trend, which requires high power semiconductor devices qualified for automotive standards. In this research project, a drive system for PMSM, which is a commonly used kind of motor in the EV applications, is designed using Infineon power modules.
Depending on your project, you may be interested in having a simulation environment where you can test your solution. In other cases, that's the only option you have since you need to wait for the supplies or works in different groups. Concerning that, simulations can provide an excellent testing bench where you can try the best and worst scenario for your solution, saving you time and money.
On this first chapter of Pic Bytes Micro, we will write down some specs and requirements to have an idea of how the final system will look like. This will also help us to select the components and divide the whole project into small tasks.
Pic Bytes Micro is an 8-bit portable arcade with a monochromatic LED screen. The project was chosen in order to learn about different engineering fields: Basic electronics, microcontrollers and programming. Some games are developed for the hardware: Snake, Tetris, Arkanoid...
