Embodiment Construction

[0023] Such as figure 1 Shown is a frequency conversion circuit of an embodiment, including a voltage conversion module 110 , a push-pull module 120 and a switch tube Q1 .

[0024] The transformer module 110 includes a transformer T1 having a primary winding and a secondary winding. One end of the primary winding of the transformer T1 is connected to the DC power supply Vcc, and the other end of the primary winding of the transformer module 110 is connected to the input end of the switching tube Q1. The control terminal of the switch tube Q1 is connected to the output terminal of the push-pull module 120 , the output terminal of the switch tube Q1 is grounded, and the push-pull module 120 controls the switch tube Q1 to be turned on and off repeatedly.

[0025] In the frequency conversion circuit, the operation of the frequency conversion circuit is controlled by turning on and off the switch tube Q1. Specifically, the push-pull module 120 controls the switch tube Q1 to be turn...

Abstract

A frequency changer circuit comprises a voltage transformation module, a push-pull module and a switch tube Q1, wherein the voltage transformation module comprises a transformer with a primary winding and a secondary winding. One end of the primary winding of the transformer is connected with a direct current stabilized voltage power supply, and the other end of the primary winding of the transformer is connected with the input end of the switch tube Q1. The control end of the switch tube Q1 is connected with the output end of the push-pull module. The output end of the switch tube Q1 is connected with the ground. The push-pull module controls the switch tube Q1. In the frequency changer, the work of the frequency changer is controlled through on-off of the switch tube Q1, concretely, the push-pull module is used for controlling repeated on-off of the switch tube Q1, so that the secondary winding of the voltage transformation module is made to output voltage which is high in frequency and pure in wave shape.

Description

technical field [0001] The invention relates to the field of power frequency conversion, in particular to a frequency conversion circuit. Background technique [0002] Electric energy is the driving force for the development of human civilization, and it is also an important indicator to measure the development of a country and people's lives. my country's electric energy production and development has been ranked among the best in the world, but it still cannot meet the needs of industrial development and people's living standards. One of the main reasons is that the waste of electric energy is relatively serious. are getting more and more attention. The traditional frequency conversion modulation method has the disadvantages of low frequency conversion and impure waveform. Contents of the invention [0003] Based on this, it is necessary to provide a frequency conversion circuit that can provide high frequency conversion frequency and pure waveform in view of the proble...
