Bipolar Dc Power Supplies

In the atx.

Bipolar dc power supplies.

In quadrants 1 and 3 a bipolar supply is sourcing power. They are fully equipped with safety functions including sinking current. They share a common ground and the output can be any combination of polarities or voltages. For example the atx power supplies used in most pcs today have multiple voltage outputs but share one common.

Aside from that the bipolar power supplies which can add ac to dc are suitable for evaluation tests and aging. While a common unipolar dc source might be able to create a 100 ms pulse width and a high performance unipolar dc source might be able to create a 1 ms pulse width a bipolar power supply often. The pbz sr bp series is a series of high power bipolar dc stabilized power supplies. In figure 1 we have an example of a bi polar power supply using two 9 volt batteries.

Another name for these is bipolar since they are able to produce either positive or negative voltage on their output terminals. These supplies can typically operate in all four quadrants and are therefore known as four quadrant power supplies. Due to the large impedance of the magnet the high frequency noise of the power supply is often less important than the stability or long term drift of the current. The pbz sr bp series are designed based on the pbz intelligent bipolar power supply series that supports large currents up to 200 a and is assembled with exclusive rack system smart rack.

Current flows out of the more positive. The following bipolar power supply systems are available.
