ENERGY CONVERSION DEVICE AND METHOD OF VOLTAGE CONTROL ON CAPACITOR OF ENERGY CONVERSION DEVICE Russian patent published in 2013 - IPC H02P27/06 H02M7/521 H02M7/53846 B60L11/12 

FIELD: electricity.

SUBSTANCE: energy conversion device consists of a linear switch connected in series with a DC source; the first capacitor connected in parallel with the DC source via the linear switch; a discharge circuit, which comprises a resistor and the first switching circuit, connected in series, and connected in parallel with the first capacitor; an energy converter for excitation of a synchronous machine; the second capacitor connected in parallel with the DC side of the energy converter; the second switching circuit connected in series between the first capacitor and the second capacitor; and a control circuit to control the discharge circuit. The control circuit controls a discharge circuit on the basis of voltage of the first capacitor and voltage of the second capacitor.

EFFECT: reduced weight and dimension parameters and cost.
