Introduction of DC power filter circuit: The circuit consists of three parts, the first part is a one-stage LC filter circuit, the second part is a common mode EMI filter, and the third part is a two-stage LC filter circuit.

LC filter is generally called passive filter. It is a traditional DC power harmonic compensation device composed of inductors and capacitors. It can filter out harmonics in the power supply one or more times and purify the DC power supply.

Common mode filtering can suppress the problem of fast transient group pulse interference with a repetition frequency of several kilohertz in some user sites.

The PCB specification is FR4 42X77X1.6MM, the high-current circuit is designed to be shortest, the path is short, it can withstand higher current, and has less interference to the outside world.

There are four types of inductors: 2A, 4A, 10A, and 20A.

Input: DC does not exceed 50V (higher voltage can replace the electrolytic capacitor to improve)

Output: DC.

Current: 2A.4A.10A.20A available on demand

Main parts specifications:

Circuit board: double-sided FR4 fiberglass board

Electrolytic capacitor: 50V 470UF dosage 2 PCS

Film Capacitor: 100NF 2PCS 470 PF 1PCS

Magnetic ring inductance: The dosage is 2PCS, (20A high current selects Fe-Si-Al),

Common mode inductance; dosage 1PCS, (20A high current use flat copper tape inductance)

Socket: 7.62 socket 2PIN 3PIN each 1PCS

This module is suitable for eliminating the DC power supply with electromagnetic interference, and can be used in automobiles, motorcycles, and DC circuits with strong electromagnetic interference.
