When [Tahmid Mahbub] recently reached for his ‘Lavolta’ BPS-305 bench supply, he was dismayed to find that despite it being a 30V, 5A-rated unit, the supply refused to output more than 15V. To be fair ...

There are a number of reasons why measuring the output ripple in switching regulators is such an important and delicate task. It is possible to receive erroneous readings while trying to measure this ...

Although variable dc power supplies might appear to be relatively simple instruments, engineers rely on them to deliver stable, precise, and clean voltages and currents, regardless of the load. To ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Power supplies are among the most popular pieces of electronic test equipment. This isn’t surprising, as controlled electrical energy is used in a tremendous number of ways. The term “bench” or ...
