Description

Technical Field

[0001] The utility model relates to the field of inverters, in particular to an inverter protection structure. Background Art

[0002] An inverter is a device that converts direct current into alternating current. There are many types of inverters, such as photovoltaic inverters and vehicle inverters. Among them, photovoltaic inverters are an important part of solar photovoltaic power generation systems, responsible for converting the direct current generated by solar panels into alternating current for use in homes and businesses. Vehicle inverters convert the direct current on vehicles into alternating current for use in vehicle electrical appliances.

[0003] The working principle of the inverter is to first convert DC power into switching pulses (AC power) through a switch / oscillation circuit, and then drive the transformer to step up the voltage to obtain sinusoidal AC power that matches the lighting load frequency, rated voltage, etc. for use by the system end users. Its components mainly include an inverter bridge, control logic, and filter circuit.

[0004] There are many ways to classify inverters. For example, photovoltaic inverters can be divided into centralized inverters and string inverters. In addition, there are sine wave inverters and square wave inverters divided by output waveform. Sine wave inverters output the same sine wave AC as the power grid, while square wave inverters output square wave AC of poorer quality.

[0005] At present, the temperature of the inverter rises when it is working, and its surface temperature can reach 60°C.
