4kw Solar Inverter UPS Function

  High-frequency machines typically consist of IGBT high-frequency rectifiers, battery converters, inverters, and bypasses. IGBT can control its on and off by controlling the drive added to the gate, and IGBT rectifier switches frequencies are typically in the thousands to tens of thousands of Hz, or even up to hundreds of thousands of Hz, much higher than the frequency machine, hence the high frequency inverter.

  In the frequency inverter circuit, the main three-phase AC input is alternated by the inductor, which is converted into a DC voltage after receiving a rectifier consisting of three SCR bridge arms, and the output DC voltage value is adjusted by controlling the on angle of the rectifier bridge SCR. Off-grid solar power is increasingly popular among local people in Syria.

Have a nice day!
