The design of a PID-controlled buck converter involves several steps:
- Power Stage Design: Select the appropriate components for the buck converter, such as MOSFET, diode, inductor, and capacitor.
- Feedback Loop Design: Use a voltage or current sensor to measure the output and feed it back to the PID controller.
- PID Controller Tuning: Adjust the parameters of the PID controller (proportional, integral, and derivative gains) to achieve the desired dynamic response and stability.
- Simulation and Testing: Use simulation tools to verify the design and perform actual testing to validate the performance.
