What is Current Harmonics?
Since more and more electronic devices used today has increased so much, the main reason for the formation of harmonics seems to be this crowd of devices. In other words, if we are to ask why harmonics happens, the basic reason lying here is the modern life itself. In addition, the use of the mod...Read more -
The difference between medium voltage soft starter and low voltage soft starter
The main circuit of the soft starter uses the thyristor. By gradually changing the opening angle of the thyristor, the voltage is raised to complete the starting process. This is the basic principle of the soft starter. In the low-voltage soft starter market, there are many products, but the medi...Read more -
Choose phase-shift or zero-crossing mode when choose scr power regulator?
Whether to choose phase-shift control or zero-crossing control when the power controller is working needs to be decided according to the specific application scenario. Zero-crossing control refers to turning on the carrier switching device every time the power supply voltage passes through th...Read more
