Problem and solution at a glance. Kinetic energy increases the DC link voltage which then drops. The DEV Dynamic Energy Supply from Koch keeps the voltage stable at a predefined level until its energy is consumed. The current course (green) shows the use of an imaginary zero line from the negative: the requirement is met until full stop (peak), then rises slightly because of the dwindling amount of energy. © Michael Koch GmbH
