filter capacitor in this role. The current pulses charging the capacitor when the diode(s) are forward-biased are generally much briefer than the time the capacitor is discharging into the load. Due to the principle of Charge Conservation in a capacitor, these pulses are therefore quite a bit higher in amplitude than the load current.
