Bob and Tim are discussing the job that they are about to start. They are at a residence and the system has a blown low-voltage fuse. Tim said, “Let’s just change the fuse and try it and see if the ...

My last two columns covered the topic of voltage troubleshooting as it applies to electrical circuits. An important point to remember is that the majority of service problems are electrically based, ...

The flyback DC/DC converter topology results in significant cost and space savings for multiple-output power supplies with high output voltage for power levels up to 100 W. Flyback topologies store ...

Sometimes a circuit requires a data link over an existing cable that doesn’t have any free conductors for a dedicated comm link. A common solution is to superimpose a high-frequency carrier modulated ...

Whether you’re aware of it or not, three-terminal voltage regulators automatically adjust power supply voltages in everything from audio consoles to distribution amplifiers to audio processing to STLs ...
