bridge rectifier earthed circuits

Dear friends,
Please explain any body why bridge rectifier negative terminal is not same voltage level to earth. In my circuit the voltage difference between negative terminal of bridge rectifier and earth is 105-110V.

Hello Naresh,

That is because the negative bridge terminal is NOT directly connected to earth or neutral. (there are diodes in the current path)
If you need it grounded, you'll need an isolation transformer.

Kind regards!
