Due to the need for highly efficient and compact power electronic converters to operate at
higher frequencies, traditional wire-wound magnetics are not suitable. This paper provides a …

Flyback and forward converters are two commonly used topologies for isolated low-power
applications. These converters are simple and cost effective and provide galvanic isolation …

With the increasing demand for flat displays, slim telecom/IT power supplies, and portable
devices, the use of planar transformers (PTs) is becoming mandatory to achieve slim …

In this paper, a thorough thermal analysis is carried out in order to find an analytical three-
dimensional (3-D) frequency-dependent thermal model of planar transformers (PTs) used in …

This paper presents the analysis of the current resonances on medium-voltage, medium-
frequency transformers due to the parasitic capacitances of the windings. Converter …

A high frequency planar transformer with integrated leakage inductance and half-turn
secondary windings is proposed for LLC isolated DC-DC converters. The primary windings …

It is a serious challenge to find the optimal winding configuration that realizes minimum
leakage inductance of multi-output multi-winding planar transformers due to the complex …

At high frequency, AC resistance of a printed circuit board (PCB) winding becomes important
and accounts for a large proportion of planar transformer losses. The winding is then …

EV on-board battery chargers must be designed to be size, weight and energy efficient. This
paper focuses on energy efficiency instead of nominal load efficiency and demonstrates that …

In this article, a stacked bridge LLC converter with the split resonant tanks suitable for high
input voltage is proposed to reduce the voltage stress of primary-side devices by half. The …
