Dear Sir, I am using Dc regulated power supply variable Linear with CV/CC mode using Transistor as series pass. Since transistors are available and want to use MOSFET or IGBT instead of transistor. Can anybody suggest how to replace transistor with FET. The unit is variable voltage and current with short circuit protection.

To get an answer, you will need to supply a circuit diagram.
A transistor needs a low voltage drive at considerable current.
A MOSFET will need a highish voltage at zero current.
Considerable redesign may well be necessary.
