Bidirectional DC

Bidirectional power systems operate as either a programmable DC source or DC load. A wide range of nominal power, voltage and current outputs are possible.

Operating in quadrants 1 and 4, each bidirectional power supply is user programmable to source or sink current from a device under test. This is in contrast to bipolar power supplies which are programmable for positive or negative voltage, supplying source current only.

The all-in-one approach allows you to test almost any DC source or DC load, as high dynamics enable users to quickly switch between quadrants. Common applications include electric drive testing, battery pack emulation, characterising DC-DC converters, battery pack cycling and super capacitor simulation.

Bidirectional ETPS products give you the advantage of regenerating excess electrical energy back to the grid whilst in load mode. In comparison, traditional electronic loads waste 100% of reusable electrical energy by dissipating it as heat. By regenerating energy, users can save significant electricity costs while eliminating thermal issues associated with traditional loads.

If a standard product doesn’t fit your requirement then our systems can be modified for a specific application, including unusual voltage ramp profiles and faster response times. Products can also be ruggedised for protection against harsh environmental conditions.
