Design Overview:
In some special applications, the power system needs to operate normally over a wide range of voltages, such as photovoltaic systems, UPS, etc. Especially in the industrial field, the voltage of the power grid is often changed by changes in the power load. It is particularly serious when the load is large.
In addition, interference spikes in the on-site environment are also superimposed on the input voltage and enter the power supply circuit together, so that the power supply chip or other components that are normally supplied under harsh environments are extremely vulnerable to damage.

At the same time, it is also convenient to use 110V voltage or 220 voltage, or to use the battery voltage directly. It can be applied to the power supply voltages of various countries in the world, including 100VAC in Japan, 230VAC in Europe, and even 120/208VAC in the United States, and batteries.
