Design of Sine Wave Inverter Power Supply Based on STM32

Article Preview

Abstract:

The paper design a high performance 20KW grid inverter based on STM processor, and describes the overall structure of the inverter, and design the hardware circuit and the software design scheme; finally produce the prototype and test. The experimental results show that: in the condition of rated power inverter can stabilize output valid values of 220V 3%, frequency is sine wave AC 50HZ, output voltage has small harmonic content and high reliability, and has a good application prospect in the field of photovoltaic power generation.
