Welcome to the CUI Inc. Thermal Management of Power Supplies product training module. This presentation will help to understand the intrinsic conversion efficiency of a power supply’s design and how the resulting losses, dissipated as heat, can best be dealt with. It will discuss ways to ensure that both the power supply and the equipment it is powering can continue to operate reliably over their rated temperature range. Furthermore, while efficiency in both electrical and thermal management terms is clearly important, dependable performance in regards to product reliability is an absolute must. Therefore, designing to mitigate potential failures caused by thermal stress is vital. This tutorial will consider the basics of how efficient heat dissipation relates to power supply performance, and how thermal stress affects reliability, and look in more detail at the evolution of methods for improving thermal management.
