Problems solved by technology
[0002] In microwave ovens of the related art, the magnetron is generally powered by boosting the voltage of the frequency converter, and the voltage of the AC source connected to the frequency converter is prone to fluctuations, so that the output power of the frequency converter is unstable, which may easily lead to Abnormal, poor user experience
[0003] In addition, the existing frequency converter needs to be equipped with a communication module to communicate with the controller of the microwave oven, and the frequency converter needs to constantly adjust the power, which makes the production cost of the frequency converter high

The invention discloses an electronic transformer and a microwave cooking appliance. Electronic transformers include rectifier modules, transformers, switch modules and control modules. The rectifier module is connected to an AC source. The transformer is connected to the rectifier module. The switch module is configured to provide on-off signals to the transformer. The control module is connected to the switch module. The control module is configured to generate a control signal to the switch module according to the preset output power to control the switching frequency of the switch module. In the electronic transformer of the frequency converter in the above embodiment, since the switch module can provide on-off signals to the transformer, it can protect the circuit when the AC source is unstable. In addition, because the control module can control the switching frequency of the switch module, In this way, the electronic transformer can stably supply power to the microwave generator, and the manufacturing cost of the electronic transformer in this embodiment is low.
Description
technical field [0001] The invention relates to the technical field of household appliances, and more specifically, to an electronic transformer and a microwave cooking appliance. Background technique [0002] In microwave ovens of the related art, the magnetron is generally powered by boosting the voltage of the frequency converter, and the voltage of the AC source connected to the frequency converter is prone to fluctuations, so that the output power of the frequency converter is unstable, which may easily lead to Abnormal, poor user experience. [0003] In addition, the existing frequency converter needs to be equipped with a communication module to communicate with the controller of the microwave oven, and the power of the frequency converter needs to be constantly adjusted, which makes the production cost of the frequency converter high. Contents of the invention [0004] The embodiments of the present invention provide an electronic transformer and a microwave cooki...
