Kepco has been know for decades for its Bipolar Power Supplies that are used in many applications like particle beam steering, magnetic field cancellation, battery simulation and testing, magnet applications, medical imaging, solar panel testing and many more. The Kepco Bipolar Power supplies operate in 4 quadrants and thus are able to source and sink power to/from the load up to high frequencies.
What is a 4 Quadrant Bipolar Power Supply
Normal Power supplies operate in a single quadrant, delivering power to a load. Kepco’s BOP (Bipolar Operational Power Amplifiers) operate in all four quadrants of the voltage-current axis, therefore their output may swing seamlessly from negative to positive voltage and the output current may also swing from positive to negative values. The result of this is that BOP will function as a source or a sink, meaning it will either deliver power to a load or absorb power from a load. In order to do that, the BOP is built as a power amplifier with a bipolar output, having a frequency bandwidth much larger than a regular power supply. The frequency bandwidth is model and option dependent.
