A Method to Embed Resonant Inductor within PCB Matrix Transformer for High-Density Resonant Converters

<p>The power electronics industry seeks more efficient power delivery and higher power density year-by-year. Resonant converters, such as the three-element resonant LLC converters, have been intensively studied and applied as DC-DC converters in many applications. One of the most demanding applications for LLC converters is data centers. Data centers consume a significant amount of power. According to some estimates\cite{jones2018stop}, data centers around the world consume approximately 200 terawatt-hours of electricity per year, equivalent to the annual electricity consumption of a country like the Netherlands. This high power consumption is primarily due to the growing number of servers and other computing equipment used in data centers and the need for cooling systems. As a result, reducing the power consumption of data centers is a pivotal goal to save costs and reduce their environmental impact. Thus, due to the high power consumption and large-scale server farms, the pursuit of efficient and dense power architecture is ongoing.</p>
