Printed Circuit Board (PCB) transformer has been widely used in low power applications. Compared with conventional litz-wire transformer, the manufacture process is greatly simplified and the parasitic is much easier to control. However, in high power applications like on-board charger for electric vehicle, no one has ever done it due to the limitation of high winding loss and high multi-layer PCB...
Isolated high output current DC/DC converters are critical for future data center power architecture. LLC converters with matrix transformer are suitable for these applications due to its high efficiency and high power density. Different matrix transformer structures are investigated. Flux cancellation can be utilized to reduce core size and loss. Synchronous rectifiers and output capacitors can be...
Coupled inductors are widely used for parallel operation of three-phase converters. By adding one coupled inductor for each phase, the circulating current between two converters can be effectively suppressed. The conventional structure of the coupled inductor is originated from DC-DC conversion and does not employ any characteristics of 3-phase system. In this paper, an integrated structure of coupled...
Coupled inductor has been widely used in voltage regulator (VR) applications for many years because it can help reducing current ripple and improving transient performance. In this paper, the coupled inductor concept is applied to interleaved totem-pole critical conduction mode (CRM) PFC converter for 6.6kW on board battery charger. The difference between negative coupling and positive coupling will...
