A METHOD FOR INCREASING POWER TRANSFERRED BY AN INTEGRATED INDUCTOR AND A RESONANT-MODE POWER SUPPLY WITH AN INTEGRATED INDUCTOR

摘要

A resonant-mode power supply comprising an integrated inductor (ZER), the integrated inductor (ZER) comprising an inductor (IR) and a transformer (TR). The main internal winding (1) of the transformer (TR) is surrounded by magnetic elements (2, 3) for closing the magnetic flux lines around the main internal winding (1) of the transformer (TR), wherein at least one magnetic element (2, 3) is surrounded by at least one auxiliary external winding (4) of the inductor (IR) arranged orthogonally to the main internal winding (1) of the transformer (TR), and the power supply being configured such that during operation the current (I1) flowing through the inductor (IR) is shifted in phase with respect to the current (I2) flowing through the primary winding of the transformer (TR).
