Why does source current reverse in single phase rectifier with source impedance?

[nitishsharmabit]

Hello folks,
Can someone explain me the source current reversal in single phase rectifier having source impedance. I understood the analysis and functionality, but having a hard time understanding the change in current in source impedance from +ve to -ve. How load voltage is zero at this instant?

Thanks

Can you posts some example circuits?

I've attached the circuit.
