Bipolar Dc Power Supplies

Bipolar dc power supplies.

Magnet power supplies should have low noise dc outputs especially in the low frequency range. Current flows out of the more positive. They are fully equipped with safety functions including sinking current. Aside from that the bipolar power supplies which can add ac to dc are suitable for evaluation tests and aging.

They share a common ground and the output can be any combination of polarities or voltages. The following bipolar power supply systems are available. These supplies can typically operate in all four quadrants and are therefore known as four quadrant power supplies. In quadrants 1 and 3 a bipolar supply is sourcing power.

Another name for these is bipolar since they are able to produce either positive or negative voltage on their output terminals. 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. In figure 1 we have an example of a bi polar power supply using two 9 volt batteries. For example the atx power supplies used in most pcs today have multiple voltage outputs but share one common.

Broadband bipolar power supplies are available for ripple testing by responding to higher frequencies. 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.
