The DC power supply is protected from back current by a buffer capacitor and a diode. This also reduces current ripple of the power supply.
Of course, if the load current feeds back a too high current to the buffer capacitor for a longer period of time, the buffer capacitor's voltage increases. This should be under surveillance.
The load current is 0 up to 0.5 s, afterwards a pulse with amplitude 50 A, an offset of -25 A, a dutyCycle of 0.5 and a frequency of 1 kHz.
