Anthony Boon, developer and user of the solidThinking Digital Power Designer, demonstrates the development steps of a Buck Converter Voltage Control, covering simulation, compensator coefficient tuning, open loop, closed loop model design & compilation, and closed loop debugging & flashing.
Introduction of Anthony Boon and overview of the series
Simulation of the control system in order to analyze the response of the buck converter in voltage mode control. The microcontroller peripherals which are needed are simulated using the peripheral simulation blocks of the Digital Power Designer.
The buck converter is simulated with the coeffiecients of the compensator being the inputs. This gives us the opportunity to better tune the coefficients based on the response of the converter.
We take the first step to control the actual converter. We run a hardware in the loop diagram in open loop.
We look into the design of the model for closed loop control of the buck converter and look into the compilation of the model with just 3 clicks.
Last part is running the closed loop control algorithm in hardware in the loop for validation. After validation we can revert to the design diagram and in just one step create a binary file that can be flashed to the controller.
