What is a bipolar (four-quadrant) power supply?

These supplies can typically operate in all four quadrants and are therefore known as four-quadrant power supplies. Another name for these is bipolar since they are able to produce either positive or negative voltage on their output terminals. In quadrants 1 and 3, a bipolar supply is sourcing power: current flows out of the more positive voltage terminal. In quadrants 2 and 4, a bipolar ...

IEC Glossary

Four-quadrant metering is the extension of this power-flow concept to energy. The flow of power will result in the registration of energy in quadrants that correspond to the power vector location.

What is four quadrant motor control and how does it work?

In order to understand four quadrant motor control it is worth starting with a very quick overview of one and two quadrant motor control. In simple terms, in one quadrant motor control the controller can apply torque only in the same vector polarity (direction) that the motor is currently running at. A 2 quadrant motor controller is reversible but the same principle applies. However, with a 4 ...
