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, and at least one energy storage element of said aircraft, 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 aircraft, 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, anda controller configured to control said switches, the controller operating by cycle of a switching period T and being configured to control at least one first switch of the first arm and at least one first switch of the second arm and at least one second switch in an identical manner but shifted by a half-period T/2 so that the first switches are open when the second switches are 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.
