| Popis: | This paper reveals how the conducted common mode noise of a boost converter can be reduced by the use of leakage inductance of coupled inductor. Specifically, it shows how the common mode impedance due to the leakage inductance of a coupled inductor can be used to reduce common mode current, and this point is experimentally verified using two kinds of inductors: a gapped core inductor with a higher leakage inductance and a gapless core inductor with a lower leakage inductance. Moreover, it is theoretically explained and experimentally verified that the proposed coupled inductor leakage inductance technique does not affect converter operation waveforms. Because the technique can be implemented simply by splitting the windings of a conventional inductor and changing the wire connections, no additional components are required, and the technique has the potential to eliminate common mode filters, as well as reduce converter costs and volume. |
