What’s the Best AC Input for Your DC Power Supply? Tuesday, July 30, 2024
An alternating current (AC) input feeds AC power into your direct current (DC) power supply. Choosing the right AC input for your power converter or switching power supply is critical for ensuring adequate performance, efficiency, and reliability. AC input refers to the type of alternative current input power that feeds into the machine. The device then converts the input voltage and input current …

Should You Consider a Bidirectional Power Supply Wednesday, June 12, 2024
The advancements in power supply technologies represent a big step forward for sustainability and flexibility. In this landscape, bidirectional power supplies are real game-changers, merging traditional power delivery with energy recovery systems to drive innovation. A Bidirectional power supply is an all-in-one solution that combines an electronic load (a power sink) and a direct current (DC) …
Use EA’s Arbitrary Function Generator to Output Custom Voltage or Current Waveforms Wednesday, May 1, 2024
Whether you are a seasoned engineer or are relatively new to electronic testing, it’s vital that you have the right equipment at your disposal. One of the most important devices you’ll need is an arbitrary function generator (AFG), which provides waveform creation capabilities. In this blog post exploring AFGs, also known as arbitrary waveform generators (AWGs), you can learn everything you need …
Battery Emulation Testing for Repeatable and Efficient Results Wednesday, April 24, 2024
How can we test battery-powered electronics? If we test with a battery or a battery pack, we are working with a voltage source that does not have a constant output. The battery output is not repeatable and must be disposed of if it is a primary battery or re-charged if it is a secondary battery. We could use a conventional power supply, but we cannot ensure that the electronics perform correctly …
