In order to realize the miniaturization and practicability of the vehicle mounted inverter, an improved vehicle inverter is designed, which includes 220V AC output and USB dual output structure. Introduces the working principle of the inverter, the application of TVS clamp technology absorption peak voltage and power consumption reduction method, put forward to use LM2596 with the voltage stabilizing circuit of dual output scheme, and using CX7131B smart chip dual USB output. At the same time, the simulation of the output voltage and output current using the saber simulation software, and equipped with the experimental validation, the results showed that the indexes of power supply to meet the design requirements, strong practicality and reliability.
