  • Method of discharging at least one electrical energy storage unit, in particular a capacitor, of an electrical circuit
    Patent number: 9742346
    Abstract: Method of discharging at least one electrical energy storage unit of an electrical circuit (1), the electrical circuit (1) furthermore comprising a switching system (2) comprising a plurality of arms (3) each extending in parallel between a positive conductor (4) and a negative conductor (5) of a DC bus (7), each arm (3) comprising in series at least two switching cells (10), in which method, to discharge the capacitor (20, 40), a short-circuit between the positive conductor (4) and the negative conductor (5) of the DC bus (7) is produced in at least two of the arms (3) of the switching system (2) so as to allow the discharge current (IDC) of the electrical energy storage unit to flow from said positive conductor (4) to said negative conductor (5).
