Problems solved by technology
[0002] At present, with the development of society, people use electrical appliances more and more frequently, and electrical appliances are becoming more and more important in life, and the use of electric current is becoming more and more diverse. Among them, the mutual conversion of direct current and alternating current is essential. However, the existing inverters directly convert DC power into AC power, but the frequency of the generated AC power cannot be changed, and another electronic device, a frequency converter, needs to be added, which increases the cost of use.

The invention discloses an alternating current-direct current converter capable of changing electric frequency. The converter comprises a machine body; a power cavity 65 is formed in the right side ofthe machine body 10; a variable-speed cavity 67 is formed in the left side of the power cavity 65; an adjusting cavity 66 communicating with the variable-speed cavity 67 is formed in the lower side of the variable-speed cavity 67; a variable-frequency cavity 68 communicating with the variable-speed cavity 67 is formed in the upper side of the variable-speed cavity 67, and a variable-speed device69 for changing the rotating speed is arranged in the variable-speed cavity 67. The converter can convert a direct current into an alternating current, the frequency of the generated alternating current can be changed at will so as to adapt to use of different electric appliances, and the use cost is reduced.
Description
technical field [0001] The invention relates to the technical field related to power supply, in particular to an AC-DC converter capable of changing electric frequency. Background technique [0002] At present, with the development of society, people use electrical appliances more and more frequently, and electrical appliances are becoming more and more important in life, and the use of electric current is becoming more and more diverse. Among them, the mutual conversion of direct current and alternating current is essential. However, the existing inverters directly convert DC power into AC power, but cannot change the frequency of the generated AC power, and need to add another electronic device, a frequency converter, which increases the cost of use. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes an AC-DC converter capable of changing the electric frequency, which can overcome the above-m...
