Abstract
A solid state radio frequency high power generator for induction heating applications uses MOSFET devices controlled at radio frequency by a current loop which is automatically corrected against the possible occurrence of a leading phase shift by a voltage-current phase shift detection loop which responds to digital signals corrected against inherent time delays.
