DC power supply: Using energy, not wasting it | KEB

DC-coupled drive systems offer an interesting solution. The DC network makes it possible to actively reuse energy in the machine instead of wasting it. This saves energy and, in the event of regenerative operating states, avoids the need for braking resistors, which would otherwise be necessary, with their thermal losses and risk of fire.
