In this paper are described some principles and new methods underlying the temperature adjustment in an laboratory electrical furnace. Due to high thermal inertia, classical Proportional-Integral-Derivative algorithms are difficult to be implemented when a high precision temperature adjustment is required. An original software algorithm written in C language performs the temperature control function, by conducting screenings for temperature values in the next future. Thus, the furnace temperature may be set with a high accuracy. The method is practically implemented and tested on a testing platform for wide bandgap semiconductors.
