Abstract
The invention discloses a multi-circuit processing type inversion system. The multi-circuit processing type inversion system is characterized by mainly comprising an inversion chip U1, a transformer T, a triode VT1, a polar capacitor C2, a polar capacitor C19, a polar capacitor C18, a resistor R14, a three-terminal integrated voltage-stabilizing circuit, a comparison amplification circuit, a voltage detection circuit, a voltage-controlled oscillation circuit and an overvoltage protection circuit. By adoption of the multi-circuit processing type inversion system, the voltage resistance and the dynamic range of the inverted voltage can be improved; in addition, the intermediate zero offset of the inverted voltage and current can be controlled to be within 0.5nA, thereby ensuring the stability of the alternating voltage output by the multi-circuit processing type inversion system; and in addition, the leakage current and the loss current of the voltage and the current in inversion can also be lowered, and the abnormal fluctuation of the output current can also be suppressed, thereby improving the load capacity of the multi-circuit processing type inversion system, namely the load capacity of the multi-circuit processing type inversion system is 80-95% of a rated load.
Description
technical field [0001] The invention relates to the field of electronics, in particular to a multi-circuit processing inverter system. Background technique [0002] The inverter system converts DC power (battery, storage battery) into AC power (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, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, 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 sy...
