In Steves' DRSSTC-1 full bridge circuit there are two bypass cap(10uf)
But for full bridge SSTC(40n60) is that cap necessary? Do I have to add it?
Cheers.

those caps are not bypass caps but snubber caps, their main use are to reduce voltage or current spike, and keep your power semiconductors alive.
