Technical Field

[0002] An inverter is an electronic device whose main function is to convert direct current into alternating current. This process is the opposite of rectification, hence the name inversion. Inverters are mainly used in solar photovoltaic systems to convert the direct current generated by solar panels into alternating current that can be used by homes or power grids. Inverters can be divided into sine wave inverters, square wave inverters, and trapezoidal wave inverters according to the output waveform. According to the operating frequency, inverters can be divided into low frequency, medium frequency, and high frequency inverters.

[0003] In the process of operating the inverter, voltage and current detection is very important. Abnormal voltage and current may cause equipment damage, fire or even casualties. Real-time monitoring can promptly detect problems such as overvoltage, overcurrent, undervoltage, short circuit, etc., trigger protection mechanisms, and avoid safety accidents. By accurately controlling and adjusting voltage and current, the inverter can convert DC to AC more efficiently, reduce energy loss, and improve the overall efficiency of the system. At the same time, maintaining stable output voltage and current is essential for the stable operation of the power grid. Overload or improper operation will accelerate the aging of the inverter and its components. Monitoring can ensure that the equipment operates within a safe range, reduce unnecessary wear and tear, and extend the service life of the equipment.
