Abstract

A power converter integrates at least one planar transformer (T1, T2) comprising a multi-layer transformer substrate and / or at least one planar inductor comprising a multi-layer inductor substrate with a number of power semiconductor switches (S7-S10) physically and thermally coupled to a heat sink via one or more multi-layer switch substrates.

Description

technical field [0001] The present invention relates generally to power systems, and more particularly to power module structures suitable for rectifying, inverting and / or converting electrical power between a power source and a load. Background technique [0002] A power module is generally a self-contained unit that converts and / or conditions power from one or more power sources to supply power to one or more loads. A power module, often referred to as an "inverter," converts direct current (DC) to alternating current (AC) for use in powering AC loads. A power module, often called a "rectifier," converts AC to DC. Power modules, commonly referred to as "DC / DC converters," step up or step down the DC voltage. A properly configured and functioning power module can perform any one or several of these functions. The term "converter" is usually applied generically to all power modules, whether inverters, rectifiers or DC / DC converters, and is used generically herein. [000...
