Abstract

The invention discloses an inversion system with stable performance. The inversion system is characterized in that the inversion system is mainly composed of an inversion chip U, a transformer T, a triode VT1, a polar capacitor C2, a polar capacitor C19, a polar capacitor C18, a resistor R14, a comparison and amplification circuit, a voltage detection circuit and a voltage controlled oscillation circuit, wherein the voltage controlled oscillation circuit is connected with the C1 pin and E1 pin of the inversion chip U and the transformer. According to the inversion system of the invention adopted, the voltage withstanding performance and the dynamic range of inverted voltage can be improved, intermediate zero point deviation of inverted voltage and current can be controlled within 0.5nA, and therefore, the stability of alternating-current voltage outputted by the inversion system of the invention can be ensured; current leakage current and current loss of voltage and current in inversion can be decreased, and the abnormal fluctuation of output current can be suppressed, and therefore, the load capacity of the inversion system can be improved, and the load capacity of the inversion system is 80 to 95% of rated load.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an inverter system with stable performance. Background technique [0002] The inverter system converts DC power (battery, storage battery) into AC (generally 220V, 50Hz sine wave). The inverter system is widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers , TV, washing machine, range hood, refrigerator, video recorder, massager, fan, lighting, etc. With the development of science and technology, the above-mentioned electronic products are also constantly developing, so the requirements for the stability and load capacity of the output voltage of the inverter system are also getting higher and higher. However, the AC voltage output by the existing inverter system is unstable after inversion; and the existing inverter system also has the problem of poor load capacity, that is, the existing inverter system is only...
