The bridge rectifier circuit uses diode 4 the the converter AC to DC, but this circuit uses zener diode as a rectifier instead of diode plain will be current in the direction of the direct bias in the cycle the first current flows through D1 to. to load and then returning the ZD2 cycle, while the other flows through D2 and then returning by the way ZD1.
R1 and C1 limit current to the C2, which has served smoothing filter output voltage again.
