Abstract

The invention is applicable to the field of household appliances, and provides a power control method and device for an electromagnetic heating device and an electromagnetic heating device, wherein the power control method is applied to an electromagnetic heating device of a half bridge topology. The method comprises the following steps of: obtaining a target power and a preset power, and comparing the target power with the preset power; and if the target power is less than or equal to a preset power, adjusting a duty ratio of a PWM control signal to enable the current actual power of the electromagnetic heating device to reach the target power. The power control method for the electromagnetic heating device provided by the invention achieves the purpose of outputting low power of the electromagnetic heating device by reducing the duty ratio of the PWM control signal when the target power is less than the preset power, without intermittent heating, so as to make food boiling and cooking better and give users a better experience.

Description

technical field [0001] The invention belongs to the field of household electrical appliances, and in particular relates to a power control method and device for electromagnetic heating equipment and electromagnetic heating equipment. Background technique [0002] Electromagnetic heating equipment such as induction cooker and induction cooker have become indispensable products in people's life. When using these electromagnetic heating devices, it is often necessary to use low power for heating. For example, when frying eggs and cooking soup, if the heating power is too high, it will cause damage to the ingredients, affecting the taste of the food and even the appetite of the user. [0003] At present, electromagnetic heating equipment usually adopts the principle of topological half-bridge heating. Generally, the higher the operating frequency, the lower the heating power. Therefore, the purpose of reducing the heating power can be achieved by increasing the operating frequen...
