DEVICE FOR FORCING TRANSIENTS IN MULTIPHASE MECHANISMS WITH ADDITIONAL ENERGY RECOVERY INTO THE POWER SUPPLY CHAIN Russian patent published in 2021 - IPC H03K17/04 H01H47/32 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and is intended to force transients when a multiphase inductive load is switched on to a DC or voltage source. Essence: the device contains a DC power source feeding the windings of a multiphase electrical mechanism, interconnected key elements, two for each winding, recovery diodes two for each winding, an electromagnetic isolation capacitor and a separation diode, an additional energy return element is introduced into the power supply circuit in the form of a Zener diode or suppressor, or varistor, which is connected in parallel to the separation diode so that its anode is connected to the anode of the separation diode, and the cathode to its cathode, moreover, the threshold breakdown voltage of the energy return element is determined by the permissible voltage of the key elements.

EFFECT: increase in the performance factor and energy efficiency of the device while maintaining the forcing function compared to the prototype due to the partial return of energy to the power source due to the introduction of an additional recovery element: an energy return element in the power supply chain.
