Could not find rtl_work.TB.vhd

Try removing -L rtl_work from the command line argument.

Your script creates a folder named rtl_work, and then maps it to the VHDL library work. There is no library named rtl_work, so it should not be listed with the -L option.

Alternatively,

vsim -t ps TB_PFC_main

should also work. Modelsim is pretty good about locating VHDL libraries.

Cheers,
