This paper analyzes the ways in which high-frequency switching power supplies generate electromagnetic interference and compares several effective switching power supply electromagnetic interference c...
1. Input voltage is too high
The input parameter of the power module is abnormal - the input voltage is too high. This abnormality can cause the system to not work properly, or even burn the circuit. ...
As we all know, the TD-SCDMA industrialization special test that ended in the middle of this year proved that the TD-SCDMA system can be independently networked on a large scale. In addition, some ad...
The operating voltage of RS-485 transceiver is low (about 5V), and its withstand voltage is also very low (-7V~+12V). Once overvoltage is introduced, it will break down and be damaged. When there is s...
Compound voltage overcurrent protection, it is a voltage compound element composed of a negative sequence voltage relay and a low voltage relay connected to the phase voltage. As long as one of the tw...
