The inversion system is provided with the processing circuit, so that the inversion efficiency of the inversion system is improved by the aid of the processing circuit and electric energy is saved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a high-efficiency inverter system based on a pulse amplification trigger circuit. Background technique [0002] Inverters convert DC power into AC power. It is widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers, TVs, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting, etc. In foreign countries, due to the high penetration rate of automobiles, the inverter can be used to connect the battery to drive electrical appliances and various tools to work when going out to work or travel. Connect household appliances to the output of the power converter to use various appliances in the car. [0003] However, traditional inverters tend to output unstable AC power during operation, which affects the normal operation of electrical appliances, and even damages electrical appliances in severe case...
