摘要： Meeting todays requirement in power supply technology demands significant technological advancement in optimizing circuit topology, components and materials, thermal and packaging designs. These requirements are being pushed mainly by continuously increasing power density and efficiency requirements. Ultimately, these trends will come to a point whereby limitations from the above mentioned technological advancements is dependent on one of the above, which is the packaging design. To realize this dependence, we need to look at the growing power systems for modern equipment out there. Let us enumerate some of the available AC adapters in terms of power densities of a 45 W adapter. Firstly, square type architecture introduced by Apple is about 7 W/in3, considering the packaging has a profile limitation whereby its AC plug is removable thus occupying relatively bigger chunk of the volume. The next one is by Asus of similar profile to Apple incorporating the AC Plug eliminating the socket assembly in the packaging; which packs about 9 W/in3. Lastly, the typical rectangular profile by Eos which is about 7 W/in3. As for this particular embodiment it is about 40% smaller in profile, in contrast to the 45 W Apple packaging, with increase power density of about 12 W/in3. Packaging design method plays a great role in achieving the above requirements for a very high density converters.

摘要： A magnetic shielding apparatus includes: a passive shield; a correction target space that is defined in the interior of the passive shield; external coils as a first coil that corrects a magnetic field in the passive shield; a first magnetic sensor; a second magnetic sensor that is arranged more inside the passive shield than the first magnetic sensor; and a control unit. The first magnetic sensor and the second magnetic sensor measure a magnetic field gradient in the passive shield. The control unit controls the external coils based on a result of the measurement performed by the first magnetic sensor and the second magnetic sensor.
