Potted power poser
Open frame or potted power module? By Frank Liang, Karl Wolf, Joseph Thottuvelil and George Alameel.
Distributed power architectures, used in a variety of communications and computing equipment, often employ board mounted power (BMP) modules to provide power conversion close to the point of use.
These modules are typically dc/dc converters that provide load level voltages from a nominal 24 or 48V input. Output power ranges from less than 1W to as much as 600W. Whilst advances in components, circuits and packaging have brought smaller, lighter and more efficient BMP modules, the increase in power density poses challenges for the packaging technology.
