【Abstract】 An experimental device of variable-frequency power supply based on DSP2812 was designed. Depending on the hardware configuration of the variable-frequency power supply,its rectifier,drive,inversion and filtering modules were also designed in detail. The software process and SPWM generation method of the system are given in this paper. The experimental results of the system are analyzed. The results show that the system has the advantages of simple hardware circuit and high precision,and can be used in subsequent experiments and practice.更多还原
