Electrical current supply circuit has windings of electric motor connected in star circuit with accessible star point forming inductive energy storage device in several switching regulator branches

摘要

The electrical current supply circuit has a switching regulator with an energy storage device and a control element, whereby the energy storage device is formed from the inductance of an electric motor. The windings (W1-W3) of an electric motor (2) connected in a star circuit with an accessible star point form the inductive energy storage device in several switching regulator branches.
