Magnetic design of LC output filter inductor in full-bridge circuit |

| Abstract: | Empirical formula was usually used by circuit engineers to design filter inductor to select core size, but the experience formula of calculation results are not accurate. In this thesis, the author taked the full-bridge output filter inductor as an example, based on the inductance of the actual working principle, the formula was derived for accurate calculation of core size. Finally a design example was given, and the calculation results can meet the requirements forcore design calculations. |
