本発明は、電磁調理器の電源回路に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a power supply circuit for an electromagnetic cooker.
＜従来技術＞

な電圧の高い電源を利用することが望ましい。<Prior art> Conventionally, single-phase 2-phase AC power source for electromagnetic cookers
Although a wire type 100V is used, when used simultaneously in an electromagnetic cooker that has two or more heating parts installed with multiple heating coils, the power consumption becomes quite large, so a power supply that is sufficiently larger than the power consumption is necessary. Power must be supplied from a power outlet with sufficient capacity. For general household appliances with relatively low power consumption, a single-phase, two-wire system with a power capacity of 100V is sufficient, but in the case of the above-mentioned induction cooker, a single-phase, three-wire system or a single-phase, 200V power supply is sufficient. It is desirable to use a high voltage power supply.

Each manufacturer must design and manufacture an induction cooker with the specified specifications.
従つて、設計の標準化あるいは部品の共通化に
よるコストダウンを図ることも困難であつた。 Therefore, it has been difficult to reduce costs by standardizing designs or commonizing parts.

The purpose of this is to enable selective setting and supply of both power sources.
