BOOST CONVERTER WITH ACTIVE POWER DECOUPLING OPERATION

摘要

The present invention relates to a boost converter capable of performing an active decoupling operation using a plurality of coupled inductor modules. The boost converter according to an embodiment of the present invention sequentially charges DC power to a plurality of coupled inductor modules formed in an interleaved structure, and then supplies the charged power to each coupled inductor module to a load, and includes a plurality of coupled inductors. The active decoupling operation is performed by supplying the power charged in the module to the buffer capacitor in the decoupling circuit or supplying the power stored in the buffer capacitor to the plurality of coupled inductor modules. Accordingly, the output capacitor for supplying a voltage to the load may be applied by replacing the electrolytic capacitor with the film capacitor.
