Problems solved by technology

Although this design scheme increases the versatility of the frequency conversion board, it needs to set up an independent power supply system for the frequency conversion board. In order to improve the anti-interference ability of the frequency conversion board power supply, it is also necessary to design an independent power supply protection circuit and power conversion circuit for the frequency conversion board. , increasing the production and operation procedures of the frequency conversion washing machine, which increases the failure probability of the frequency conversion washing machine

Abstract

The embodiment of the invention provides variable-frequency electronic equipment, a control device and a driving method, and relates to the field of electric appliance design. The complete machine fault probability of the electronic equipment can be reduced. According to the control device, the first end of a main control module is connected with the first end of a power conversion module, the second end of the main control module is connected with the first end of a first switch, and the third end of the main control module is connected with the first end of a frequency conversion module; thesecond end of the first switch is connected with the second end of the power conversion module, the third end of the first switch is connected with the second end of the frequency conversion module,and the third end of the frequency conversion module is connected with the third end of the power conversion module; the power supply conversion module is used for providing working voltage for the main control module and providing the working voltage for the frequency conversion module through the first switch; and the main control module is used for controlling the first switch to be switched off when the variable-frequency electronic equipment is in a standby state, so that the variable-frequency module stops working. The control device is used for the frequency conversion electronic equipment.

Description

technical field [0001] The invention relates to the field of electric appliance design, in particular to a frequency conversion electronic device, a control device and a driving method thereof. Background technique [0002] In the current design of frequency conversion washing machines, in order to meet the general requirements, the design scheme of main control and frequency conversion is usually adopted, that is, the control circuit is designed as the main control circuit and frequency conversion circuit, which are respectively deployed on the main control board and frequency conversion board. The frequency conversion board can As a general-purpose circuit board, it is applied to different control circuits. Although this design scheme increases the versatility of the frequency conversion board, it needs to set up an independent power supply system for the frequency conversion board. In order to improve the anti-interference ability of the frequency conversion board power s...
