March 1, 2022 - Vista, California - Axiom Test Equipment, an electronic test equipment rental and sales company has published a very unique and helpful new blog post entitled "Believe in the Benefits of Bidirectional Power Supplies." A bi-directional DC power supply makes it possible to evaluate how changes on supply voltage, current, or power affect the performance of a device under test.

A bidirectional DC power supply is often used in CV or CC mode to simulate a rechargeable battery for a device under test, to better understand how a device or circuit will operate when its voltage fluctuates or drops below its nominal operating current or power level. With its bidirectional capabilities a regenerative DC power supply simplifies testing of such components as motor inverters, batteries, bidirectional on-board chargers (BOBCs), and bidirectional DC-to-DC converters without having to switch connections when testing the reverse current as with a conventional DC power supply. At Axiom we carry a wide variety of these power supplies, which includes the Elektro-Automatik PSB1000 series, 62000D Chroma series, and the RP79000 Keysight series.

 Learn more about how to pick the bidirectional power supply by reading the full blog post on Axiom's website.

Power supplies are among the most essential test equipment units, serving as energy sources for many measurements. An earlier blog, "Perusing Specs for Power Supplies and Electronic Loads," provided guidance for choosing separate power supplies and electronic loads. But power supplies and electronic loads are also available as a single unit, integrated as a bidirectional power supply with many benefits working together. Also known as regenerative power supplies, bidirectional power supplies can be programmed to evaluate many different electronic energy systems, such as rechargeable batteries in electric vehicles (EVs) and hybrid EVs (HEVs). They are also useful for testing the energy circuits and systems in unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), and many other drones with electric-powered drives.

A bidirectional power supply typically incorporates an AC-to-DC converter, DC-to-DC-converter, and a regenerative electronic load in a one rack-mount unit housing. A traditional electronic load converts energy channeled to it into heat. At high power levels, large heatsinks are needed for proper thermal management. In contrast, the regenerative electronic load in a bidirectional power supply can return most of the electronic energy sent to it back to the source, such as a power grid or battery. It can perform what is known as two-quadrant power testing, working as both a power source and electronic load or sink. By returning power instead of converting it to heat, a bidirectional DC power supply achieves higher efficiency and can handle higher power levels with smaller size and weight than conventional separate power supply and electronic load.

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
