MODULE FOR VOLTAGE TRANSFORMATION BETWEEN HIGH-VOLTAGE ELECTRIC MAINS AND ENERGY STORAGE ELEMENT Russian patent published in 2016 - IPC H02J7/34 

FIELD: electronic equipment.

SUBSTANCE: module for converting voltage between a high-voltage DC electrical network and at least one energy storage element of an aircraft is configured to reversibly convert between DC voltage E of high-voltage electrical network of aircraft and DC voltage V_s of energy storage element of aircraft. Voltage V_s is floating relative to voltage E and is centered relative to aircraft weight. Module comprises an input module comprising two filters, each of which is configured to receive DC voltage E/2, first arm and second arm comprising switches, and controls for said switches. Control means operate in cycles with period T and are designed to control at least first and second switches identical but shifted by half-period T/2 so that first switch is open when second switch is closed, and vice versa.

EFFECT: reliable energy storage element charging and discharging.
