A Bipolar power supply is a power supply that can output both positive and negative poles. It is also called a four-quadrant power supply because it can operate with both polarities for voltage and current. If the voltage and current are in the same direction, it is a source operation; if they are opposite, it is a sink operation. In addition to DC operation, sine waves and arbitrary waveforms can be operated at high speed.

At Matsusada Precision, a four-quadrant power supply with a built-in signal source is called a bipolar power supply, and one that operates by amplifying signals from an external source is classified as a bipolar amplifier. Bipolar amplifiers capable of high-voltage output are also classified as high-voltage amplifiers. When considering a bipolar power supply or bipolar amplifier, select a high-speed bipolar amplifier that can drive more than the required frequency bandwidth and speed as well as output power.
