In our previous discussion, we Analysis the optimization of magnetic core parameters. Today, we will proceed with the Core saturation prevention design . 3) . Core saturation prevention design After the magnetic core saturates, the load voltage waveform distorts and exhibits a spike waveform. Voltage spikes may damage the circuit, while the magnetic core generates heat and vibrates, causing s...

In our previous discussion, we Analysis the core saturation prevention design. Today, we will proceed with the Energy harvesting performance test.   4) .Energy harvesting performance test When the current is in the range of 50~3000 A, CT can provide a secondary voltage of 7 V or more for the load, which meets the starting voltage of the subsequent circuit. Therefore, only one test is nee...

What’s about Common Mode Choke Common modechoketypically consist of a magnetic core and two sets of winding. Visually, they appear as two sets of copper wires wound around a ring core, and they also come in different structural designs such as UU-type, and chip-type. Common-modechoke are usually connected in series on the L line and N line of the power supply. Their main function is...

For same 6.8mH common mode inductors, why the performance difference? During EMC filtering design ,engineers may encounter such problem: two similar size common mode chokes, both with indunctance 6.8mH, rated current 1A, the actual test results are different, one can pass the conduction test, while the other insufficient suppression ability in certain frequency bands, and even has a significant de...
