MODULE FOR CONVERTING VOLTAGE BETWEEN A HIGH-VOLTAGE ELECTRICAL NETWORK OF AN AIRCRAFT AND AN ENERGY STORAGE ELEMENT
First Claim
1. A module for converting voltage between a high-voltage electrical network of an aircraft, especially a high-voltage DC network, and at least one energy storage element of said aircraft, especially a super-capacitor, said conversion module being able to reversibly perform a conversion between a DC voltage E of the high-voltage electrical network of the aircraft and a DC voltage VS of the energy storage element of the aircraft, said voltage VS of the aircraft storage element being floating with respect to the voltage E of the high-voltage electrical network of the aircraft and centered with respect to the earth of the airplane, the module comprising an input module, comprising two filters each able to receive a DC voltage E/2, a first arm and a second arm comprising switches, and control means for said switches, the control means operating by cycle of a switching period T and being able to control at least one first switch and at least one second switch in an identical manner but shifted by a half-period T/2 so that the first switch is open when the second switch is closed and vice versa.

Abstract
A module converting voltage between a high-voltage electrical network and at least one energy storage element an aircraft, the conversion module configured to reversibly convert between a DC voltage of the high-voltage electrical network and a DC voltage of the energy storage element, the DC voltage of the energy storage element floating relative to the DC voltage of the high-voltage electrical network and centered relative to the mass of the aircraft, the module including an input module including two filters each capable of receiving a DC voltage, a first arm and a second arm including switches, and a mechanism controlling the switches, operating per cycle of a switching period and capable of controlling at least one first switch and at least one second switch identically but offset by a half-period, whereby the first switch is open when the second switch is closed and vice versa.
