INDUCTION HEATING APPARATUS INCORPORATING AN INVERTER CIRCUIT CAPABLE OF BROAD OUTPUT CONTROL

摘要

Title of the Invention INDUCTION HEATING APPARATUS INCORPORATING AN INVERTER CIRCUIT CAPABLE OF BROAD OUTPUT CONTROL There is provided an improved induction heating apparatus wherein a magnetic body itself is caused to generate heat by an eddy current induced on the crossing of a magnetic field generated by a coil with the magnetic body. The apparatus incorporates an inverter circuit unit capable of broad output control which performs a zero crossing detection of a heating coil voltage and which performs a pulse width control of a transistor in synchronism with the outputting of said zero crossing detection.
