AC EMI Power Filter AC High Frequency Filter Module
Anti-electromagnetic Interference Filting DC Component 2A/4A/8A
Description:
The circuit consists of two parts, the first part is RFI DC blocking circuit, and the second part is two-stage composite EMI electromagnetic interference filtering circuit.
1> RFI DC blocking circuit: it can eliminate the interference of AC 220V mains electricity caused by the DC components of inverter air conditioners, switching power supplies, refrigerators, chargers and other household appliances. The RFI DC blocking circuit built with diodes and capacitors is used to eliminate and block the DC component in the mains AC power supply, so as to prevent the transformer from magnetic saturation or static current increase due to the DC component. Adding RFI DC isolation circuit can significantly improve the quality of power supply, eliminate and suppress the hum of transformer, and improve the quality of power supply.
2> The two-stage composite EMI filter circuit has better noise filtering effect because of two-stage filtering. It can restrain the fast transient group pulse interference with repetition frequency of several kilohertz in some user sites.
The shortest design of the high-current line, the short path, can withstand larger current, and has less interference to the outside world. The inductors are available in three specifications: 2A, 4A, and 8A .
