Abstract
The invention discloses an inverter power supply. The inverter power supply comprises a direct-current battery, a solar cell, a wide-range power switch, a mainboard, an insulated gate bipolar transistor (IGBT), a choking coil and a filter. The inverter power supply is characterized in that the solar cell outputs two lines of direct currents, one line of the direct currents and the direct-current battery are output to the wide-range power switch, and the other line of the direct currents are output to the insulated gate bipolar transistor (IGBT); the direct currents which are processed by the wide-range power switch are then output to the mainboard, the direct currents are driven to the insulated gate bipolar transistor (IGBT) by the mainboard, the insulated gate bipolar transistor (IGBT) outputs the direct currents to the choking coil and the filter, and then the obtained direct currents are converted into alternating currents which are provided for an inverter system. Through the adoption of the inverter power supply, the problem that equipment is damaged caused by voltage transient, under-voltage, overvoltage and the like is effectively solved.
Description
Technical field
The present invention relates to a kind of inverter.
Background technology
Power technology especially variable frequency power supply technology is an engineering that practicality is very strong, serves all trades and professions.Power electronic technology is one of best applications technology of electric energy.The subjects fields such as that current power technology has merged is electric, electronics, the system integration, control theory.Along with the modern information technologies revolution that computer and mechanics of communication develop, provide vast potential for future development to power electronic technology, also have higher requirement to power supply simultaneously.The generally use in electronic installation along with frequency conversion and inverter, common power, in the error that when work produces, can affect the accuracy of whole system.Power supply can cause a lot of adverse consequencess in use, and countries in the world have proposed different requirements and formulated a series of Product Precision standard power supply product one after another.Only have the product standard of meeting, can come into the market.The development that inverter is current, mainly towards higher stability and distortion rate and better dynamic characteristic; Better environmental-protecting performance; Intellectuality and high reliability; The future developments such as application widely.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is to provide a kind of inverter of practicality, has effectively solved the shortcoming that causes device damage due to voltage transient, under voltage, overvoltage etc.
For reaching above-described object, a kind of inverter of the present invention is taked following technical scheme:
A kind of inverter, comprise direct-flow storage battery, solar cell, wide-range power switch, mainboard, insulated gate bipolar transistor (IGBT), choke and filter, it is characterized in that, described solar cell output two-way direct current, one road direct current and direct-flow storage battery are exported to wide-range power switch, another road direct current is exported to insulated gate bipolar transistor (IGBT), described wide-range power switch will be exported to mainboard after Direct current treatment, driven to insulated gate bipolar transistor (IGBT) by mainboard, direct current is exported to choke and filter by described insulated gate bipolar transistor (IGBT), then will obtain direct current becomes after alternating current, offer inversion system.
Adopt as above the present invention of technical scheme, there is following beneficial effect:
Effectively solve the shortcoming that causes device damage due to voltage transient, under voltage, overvoltage etc.
