Abstract

The invention provides an inverter system based on a three-terminal integrated voltage stabilizing circuit. The system mainly consists of an inverter 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 comparative amplification circuit, a voltage detection circuit and a voltage-controlled oscillation circuit connected with a C1 pin and an E1 pin of the inverter chip U1 and the transformer T. The system can improve the voltage resistance and widen the dynamic range of post-inversion voltages and control the intermediate null offset of post-inversion voltage currents within 0.5nA, thereby guaranteeing the stability of alternating voltages output thereby. The system can also reduce leakage currents and loss currents of voltage currents in inversion and restrain exceptional fluctuations of output currents, so that the load capacity of the system is improved and is 80-95% of a rated load.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an inverter system based on a three-terminal integrated voltage stabilizing circuit. 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 ca...
