Imagine a power bank that not only charges your phone (discharging) but can also suck power back from it (charging). It even lets you decide how fast it "eats" or "spits" electricity, while reporting its "weight" (voltage/current data) in real time. That's a bidirectional programmable power supply!
Its superpowers:
① Eat & Spit Freestyle
"Need to power something? "It becomes a "generator", pumping out precise current (e.g., charging EV batteries).
"Need to recycle energy?" It transforms into a "vacuum cleaner," sucking electricity back to the grid (e.g., testing solar panel output).
② Tweak Parameters Like Your Oven
Set voltage, current, and power via computer – like making delicious food in an oven: "Baking cake at 180 ℃ today, 220 ℃ medium heat roasted chicken wings tomorrow!" Understand and execute in seconds.
③ Energy saving and environmental protection expert
Recycles 80% of used energy – thriftier than a housewife! (Traditional power supplies: "Power gone? Oh well." This guy: "Nope, I'll regurgitate it!")
Bidirectional Programmable DC Power Supply Working Principle
It operates using power electronics circuits (like MOSFETs/IGBTs) to dynamically switch between sourcing and sinking DC power. A microcontroller adjusts voltage/current via PWM control, enabling programmable energy flow direction (charge/discharge) while recycling up to 90% of absorbed energy back to the grid or storage. Real-time feedback ensures precision in testing, battery emulation, and renewable energy simulations.
Where is it needed?
EV factories: Pretend to be a battery and test how far cars can go.
Labs: Simulate a harsh environment to test the performance of solar panels.
Phone makers: Let the battery be repeatedly charged and discharged 1000 times to see if it will break.
One-liner summary:
It's the Swiss Army knife of power supplies – charges, discharges, goes soft/hard mode, saves money/energy, and doubles as the ultimate toy for Research workers and engineers!
