Hi,

I used SPDT switch to enable/disable one of the topologies.
When I tried yesterday with single stage of rectifier topology, it was working fine.

Today, I simulated the similar concept with multi-stage rectifier for both topologies. I see some strange results.

Can you pls explain why there is change in behavior of signal?

In this zip file, 1.png is the waveform which I observed for the SPDT switch with no load.
multi_1.png is the plot when load (rectifiers) are present. multi_2.png is the circuit diagram of complete design and the last fig is the zoomed version of SPDT switch.


Request you to pls help me.
