Electrical device, and control device and control method thereof

Abstract

The invention discloses a control device of an electrical device. The control device is provided with a first power supply, a second power supply and a third power supply. The power of the first power supply is smaller than the power of the third power supply. The second power supply is formed through serial connection of a plurality of farad capacitors. After the electrical device enters a low-power-consumption mode, a main control chip cuts off connection of the third power supply and a power-supplying power supply through a second switching circuit and then uses a first switching circuit and a commutation circuit to control the first power supply and the second power supply to supply power alternatively. The control device reduces effectively the power consumption of the electrical device and has the advantages of being safe, environment friendly and long in service life. The invention also discloses the electrical device with the control device and a control method applied to the electrical device.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment control, and in particular relates to an electrical equipment, a control device and a control method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, more and more electrical equipment, such as air conditioners and televisions, appear in people's lives. These electrical devices usually have low power consumption modes, such as sleep mode and standby mode. [0003] At present, when electrical equipment is in low power consumption mode, the main board (mainly including the main control chip) is powered by the switching power supply. The switching power supply has high efficiency during operation, which can reach more than 90%. less efficient. Therefore, when the electrical equipment is in the low power consumption mode, large losses will be generated. How to reduce the power consumption of the elect...
