Abstract

The invention provides an integrated device and a power conversion apparatus including the same. The integrated device includes a substrate, a die disposed inside the substrate, at least one capacitor disposed on a surface of the substrate, where the die and the at least one capacitor are electrically connected. The power conversion apparatus comprises at least one integrated device according to the preceding embodiment of the present invention. The compact design of the integrated device enables a high-frequency, efficient, high-power-density power conversion device.

Description

technical field [0001] The present invention relates to integrated components for power conversion, and in particular, to high frequency, high efficiency, high power density power conversion devices with integrated components. Background technique [0002] Power conversion is an important issue in many different electronic applications. Power losses limit the miniaturization of switch-mode power supplies. However, how to convert electricity efficiently is crucial to almost every kind of power conversion. In particular, it is desirable to keep possible power losses associated with power conversion as low as possible while attempting to keep the footprint required for power conversion as small as possible. [0003] Increasing switching frequency is the main way to reduce area to increase power density. In this way, passive components such as capacitors, magnetic components can be smaller. However, the efficiency drops more or less because there is more heat to dissipate. ...
