Abstract

A low-core-loss transformer for high transfer ratio and high power density applications can have five pillars including four corner pillars and at least one center pillar between magnetic metal plates. The center pillar provides an additional flux path to reduce thermal and core losses and improve efficiency. Magnetic flux density may be further reduced by having multiple central pillars in an N-track configuration in several kinds of symmetrical arrangements. The low-core-loss transformer achieves a flexible voltage transfer ratio. The ratio can be either even or odd numbers. An odd ratio design is able to fulfill the requirement of future data centers to supply a 400-volt high-distribution power bus. The transformer windings can be traces on a Printed Circuit Board (PCB) that integrate electronic components for a compact and modular design.
