EMI suppression filter class D, EMI suppression

Reduce the ripple of the power supply and reduce the interference caused by the power supply.

This board can be used in low-voltage circuits (0V - 50V) such as power amplifier boards, automotive devices, industrial control boards, DC devices, etc.

The circuit is flexible to use. If the suppression effect does not meet the requirements, it can be connected in series at multiple levels to increase the inhibition capacity. If the working current of the circuit board does not meet the requirements, it can be connected in parallel with multiple blocks to increase the output current.

For the PCB with positive and negative power supply, two blocks can be overlapped to form a positive and negative energy interference suppression board.

An EMI filter suppresses the high-energy interference voltages from the line. First of all, the mains choke, which is integrated in the EMC mains filter, reduces the low-frequency interference. Other components integrated in the EMC line filter then filter out the high-frequency interference.
