Control of a DC-DC converter to supply a constant current to a pulsed load

A method comprising, for a power supply which has an output electrically coupled to at least one pulsed load and to an output capacitor:

• generating a signal (VOV) informative of a voltage (VOUT) at the output of the power supply,
• generating a signal (VIload) informative of a current (Iload) required by the at least one pulsed load, wherein, for at least one given period of time, the current (Iload) comprises a series of pulses,
• generating a signal (VIin) informative of a current (Iin) at an input of the power supply,
• feeding the signal (VOV), the signal (VIload) and the signal (VIin) to a controller of the power supply, and
• controlling, by the controller, the current (Iin) such that the signal (VIin) which is informative thereof, meets a predefined relationship with the signals (VOV) and (VIloud), wherein said controlling enables the power supply to generate, at its output, a current (Iout) in at least part of the at least one given period of time, said at least part of the at least one given period of time comprising a plurality of pulses of the series of pulses,
• wherein the current (Iout), which is used to charge at least intermittently the output capacitor, Lout is constant according to a stability criterion over the at least part of the at least one given period of time.
