When it comes to testing power supplies, it’s useful to have a dummy load to put the gear through its paces. While it’s possible to just use some old heating elements or other big resistors, an active ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

Bench electronic loads are usually rated for voltages less than 100V, which make it difficult to test high-voltage power supplies. This Design Idea offers an alternative: an inexpensive electronic ...

When it comes to testing power supplies, it’s useful to have a dummy load to put the gear through its paces. While it’s possible to just use some old heating elements or other big resistors, an active ...

In general terms, power amplifiers (PAs) used in communications systems must be large enough to amplify envelope peaks. This leads to amplifiers designed to offer the best efficiency at peak power ...
