摘要：

The letter presents a patent of lateral coupled inductor structure and its applications in single-phase and multiphase dc-dc converters. The central processing units (CPUs), graphics processing units (GPUs), and field-programming gate arrays (FPGAs) in the latest servers and artificial intelligence (AI) systems are powered by multiphase dc-dc switching converters and require high current, small size, fast transient response and high efficiency. This single-turn lateral coupled-inductor structure reduces magnetic core size through inverse coupling and minimizes inductor direct current resistor power loss for high-current applications. The coupled inductor can be embedded inside a motherboard or a power module. The letter illustrates different implementations of the patent and provides solutions to the AI systems that require high current and small volume of the power converters.
