A directional coupler is used to sample a small amount of input signal power for measurement purposes. Port 1 is the input port; port 2 is the output port; port 3 is the coupled port; port 4 is the ...

Around the world, over 200 countries use Alternating current (AC) power as a convenient power source for many electronics. However, the power around the world is not the same in each location, ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

Switching dc-dc power supplies are prolific in today's consumer electronics. Most applications use an input source that provides a positive dc voltage referenced to system ground. These sources often ...

Input protection for switched mode inverters and converters affects an increasing number of sectors, writes Martin Keenan of Avnet Abacus. Switched mode inverters and converters form the heart of many ...
