Behaviour of series and parallel resonant inverters for induction heating in short-circuit conditions
ABSTRACT Series and parallel resonant inverters are the common structures
in high power industrial generators for induction heating applications.
In practical working conditions, short-circuiting of the heating coil is
very common, producing normally overvoltages that can damage the power
transistors of the inverter if no special precautions are taken. The aim
of the paper is to show the mechanism of how overvoltages are generated
under short-circuit conditions of the heating coil for series as
