INDUCTION-HEATING COOKWARE

摘要

When simultaneously driving two or more inverter circuits (9) among multiple inverter circuits (9), a control means (25) drives the applicable inverter circuits (9) using the same frequency, obtains currents output from the respective inverter circuits (9) driven, and controls the driving of the inverter circuits (9) so as to reduce the phase differences among the respective output currents obtained. A load determining means (26) determines a load on the basis of the output currents detected by output current detection means (28) of the driven inverter circuits (9) and input power or output power detected by a power detection means.
