Abstract

The invention discloses an integral control inverter, which comprises an isolation hardware current limiter, an LC filter, a protection circuit breaker and a short-circuit protection circuit. The isolation hardware current limiter is connected with the LC filter, the LC filter is connected with the protection circuit breaker, and the input end of the protection circuit breaker is connected with aninverter power supply. The isolation hardware current limiter is connected with the short-circuit protection circuit. The output end of the short-circuit protection circuit is electrically connectedwith a bias ring and a voltage control ring. According to the invention, the bandwidth can be reduced to less than 10Hz, and the anti-interference capability of the inverter power supply and the output voltage precision of the power supply are improved. Meanwhile, the output volt-ampere characteristic curve of the power supply can be adjusted, the overload and short-circuit resistance of the powersupply is improved, the output voltage direct-current bias is reduced, the power supply output precision is improved, the current waveform is topped when the output of the power supply is short-circuited, the volume and the weight of an output filter inductor are reduced, and popularization and application of the integral control inverter are facilitated.

Description

technical field [0001] The invention relates to the technical field of DC / AC conversion power supply, in particular to a control inverter for changing 190V direct current into 115V alternating current, specifically an integral control inverter. Background technique [0002] With the development of aviation conversion power supply, the requirements for inverter power supply on the aircraft are getting higher and higher, especially when it is used as an emergency power supply, safety is the first indicator, so it is required to have high anti-interference ability and high-precision output; therefore, this The product is used as an emergency power supply in the AC secondary power supply, and the technology to improve the anti-interference ability and precision is an inevitable trend of development. Contents of the invention [0003] The purpose of the present invention is to provide an integral control inverter to solve the problem that the existing inverter power supply syst...
