Claim:
1. A method for discharging at least one electrical energy storage unit comprising, a capacitor or a standalone source of electrical energy of an electrical circuit, the electrical circuit further comprising a switching system comprising a plurality of legs each extending in parallel between a positive conductor and a negative conductor of a DC bus, each leg comprising at least two switching cells in series, the method comprising: a first step during which a short circuit is produced in a first leg and a second leg so as to define a path allowing the discharge current to flow between the positive conductor and the negative conductor of the DC bus; and a second step during which a short circuit is produced in the second leg and another leg so as to define a path allowing the discharge current to flow between the positive conductor and the negative conductor of the DC bus.
