Research on control system code generation technology of LLC resonant converter for rare earth electrolytic power supply

Targeting the problems of low efficiency of digital control of DC/DC converter in the traditional rare earth electrolytic power supply system, and weak correlation between writing control algorithm code and hardware in manual code development mode. An automatic code generation method based on model-based design (MBD) is proposed to realize the digital control strategy of LLC resonant converter by taking the LLC resonant converter as the main circuit model and establishing a Simulink closed-loop control system for code generation. To ensure the accuracy and reliability of the control system model, the algorithm code verification is combined with in-loop testing, and finally the control system code generation is carried out. The results show that this method can shorten the development cycle of the DC/DC converter control system code, improve development efficiency, and provide an efficient development method for the development of the control system of rare earth electrolytic power supply.
