In recent years, digital control has been widely used in the field of power electronics. Automatic code generation, as a graphical software writing method, has brought great convenience to the writing of electronic control software due to a series of advantages such as easy to write and easy to simulate and verify. Simcoder in PSIM is an automatic code generation software that enables the automatic generation of complete DSP control program projects. In this article, the current and voltage loops of a typical average current controlled BUCK circuit are designed as an example, and the use of PSIM and Simcoder is described in detail. Based on the main circuit and Matlab parameter calculations, the model is simulated and the self-generated code is downloaded into the TMS320F28335 to test the output voltage and current of the hardware circuit. The circuit output has the advantage of stable output voltage with small steady-state error and low voltage overshoot, demonstrating the practicality and efficiency of automatic code generation on this project.
