KNE BDCC Series

The new KNE-BDCC series of bidirectional DC-DC converters delivers high power in a very compact format: up to 250 kW in just 28 height units (RU), while requiring only half the width of a 19″ rack – allowing a DC-DC converter stage with up to 500 kW to be implemented in 28 RU.

Here too, the user gets two devices in one: a DC power supply (source) and an electronic DC load (sink) with energy recovery. This means that the devices provide two-quadrant operation as standard, while the two channels enable a circular flow of energy from the source via the device under test to the sink. This allows energy costs to be optimized in numerous applications: once the circuit is running, only the losses need to be compensated for by supplying additional energy.

The internal electronic load ensures high voltage dynamics by discharging the required capacitance at the DC connection, while simultaneously acting as a load for a connected source. This creates a fully-fledged regenerative load for systems with power levels of up to the megawatt range.

In source operation, the device functions as a controllable, flexible energy source. It combines the advantages of both devices while avoiding the disadvantages of separate solutions in terms of weight, space requirements, costs, and integration into test software.
