INTEGRATED STRUCTURE FOR A MATRIX TRANSFORMER

摘要

An integrated compact structure (80) for housing a magnetic transformer and associated electrical and magnetic components to provide high power density, distributed thermal heat sinking and optimal terminal and component placement for high frequency operation includes a chassis body (82) having a base (98) and side walls (84, 86) wherein the semiconductor switching components may be mounted in close proximity to the magnetic elements to minimize lead lengths. The chassis further includes a number of heat sinking stubs (122) arranged to mount rectifying semiconductor components (128) in close proximity to the magnetic elements and in such a manner as to serve as a heat sink such that there are no localized hot spots wherein heat is substantially evenly distributed across the chassis. The terminals (130, 132, 134) connecting to the semiconductors and to the magnetic circuit elements are optimally located for high frequency operation.
