Title:
INDUCTION HEATING COOKER
Document Type and Number:
Japanese Patent JP2006351371
Kind Code:
A
Abstract:

To precisely control heating power in an induction heating cooker.

This cooker is constituted so that a high frequency current generated at an inverter circuit (3) is supplied to a serial resonance circuit (4) formed by a heating coil (27) and capacitors (28, 29) for inductively heating a heated object (31), and the heated object is heated. Firstly, a coarse adjustment of input power is carried out by varying a switching frequency of the inverter circuit, and next, the input power is made to coincide with a target power value by a fine adjustment of a DC voltage supplied to the inverter circuit.
