Title:
ELECTROMGNETIC INDUCTION HEATING DEVICE
Document Type and Number:
Japanese Patent JP3687028
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating device aiming at the reduction of the cost of circuit by commonly using an arm formed of plural switching elements, a current detecting unit for heating coil and a resonance capacitor in plural inverter circuits.
SOLUTION: A full-bridge type inverter circuit for converting the direct current voltage from a smoothing capacitor 3 to the high frequency voltage is formed of a first arm 15 and a second arm 16. The other full-bridge type inverter circuit is formed of the second arm 16 and a third arm 17. A control circuit 14 is provided to control the drive of each driving circuit so as to commonly use the second arm 16 in both the inverter circuits.
