Design of Three-phase Inverter Based on STM32

This paper studies and designs a three-phase inverter based on single chip microcomputer. Its main controller uses 32-bit arm series single chip microcomputer STM32F103. The inverter part uses three-phase half bridge. The modulation mode selects SPWM modulation technology of third harmonic injection, and uses average value feedback control at the same time. On the basis of theoretical analysis, the simulation model and physical prototype are built. Through simulation and physical test, the expected design objectives are obtained. On the basis of meeting the output of band resistive load, the cost of inverter is reduced and the reliability of use is improved.
