MODULE FOR CONVERTING VOLTAGE BETWEEN A HIGH-VOLTAGE ELECTRICAL NETWORK OF AN AIRCRAFT AND AN ENERGY STORAGE ELEMENT

摘要

The invention relates to a module for converting voltage between a high-voltage electrical network of an aircraft, in particular a high-voltage direct current network, and at least one energy storage element of said aircraft, in particular a supercapacitor, said conversion module being characterized in that same is capable of reversibly converting 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 DC voltage Vs of the energy storage element of the aircraft being floating relative to the DC voltage E of the high-voltage electrical network of the aircraft and centered relative to the mass of the airplane, the module including an input module including two filters each capable of receiving a DC voltage E/2, a first arm and a second arm including switches, and means for controlling said switches, the control means operating per cycle of a switching period and being 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.
