Tianyi switch - the principle of electromagnetic interference generation and three control technologies of switching power supply
Generation and transmission of electromagnetic interference
There are two ways of electromagnetic interference transmission: one is conducted transmission and the other is radiated transmission. Conducted transmission is a complete circuit connection between the interference source and the sensitive equipment, and the interference signal is transmitted to the receiver along the connected circuit.

Tianyi switch - the difference between high-voltage load switch and high-voltage isolation switch
1. The high-voltage load switch can be broken with load and has the function of self-extinguishing arc, but its breaking capacity is very small and limited.
2. The high-voltage isolation switch is generally not able to break with load, there is no arc extinguishing cover in the structure, and there is also an isolation switch that can break the load.

Tianyi switch - the high and low voltage division of low voltage switch
36V is a safe voltage, but it cannot be used as a standard for dividing high and low voltages. There are two ways to divide high and low pressure:
1. According to the rated voltage: the rated voltage is 1000V and below is called low voltage; The rated voltage of 1000V or more is called high voltage.
2. According to the voltage of the equipment to the ground...
