I was just reading a LinkedIn message regarding methods that could be used to load-test a power supply. The original poster wanted a method to do some active load testing inexpensively. He wanted to ...

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 ...

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 ...

Unlike passive systems, active load-pull systems make it possible to overcome loss and reach all parts of the Smith chart. The classical Doherty architecture illustrated in Figure 1 consists of Main ...
