Description

technical field [0001] The invention relates to the field of electronics, in particular to a fast inverter system based on triode common-emitter symmetrical amplifying circuits. 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, the currently used inverter system tends to cause fluctuations in the current when amplifying the converted AC power, which has a great impact on the use of electrical appliances, an...
