ABSTRACT:
An induction heating unit including inverter circuit means comprised by a gate controlled thyristor and commutation circuit coupled together in circuit relationship and excited from a set of power supply terminals connected to a source of excitation potential. An induction heating coil is coupled to and excited by the inverter circuit means in a manner such that the loading on the induction heating coil determines at least in part the operating frequency at which the inverter circuit means operates. Gating circuit means comprised by a gating signal generator and enabling circuit means are coupled to and control turn-on of the gate control thyristor with the gating circuit means comprising a feedback sensing circuit coupled to the induction heating coil for deriving a feedback trigger signal synchronized with the frequency of operation of the commutation circuit.
