Sew inverter is not a single part, but a perfect and excellent product with multiple parts assembled together. The functions of each part are different, and it needs to be connected after assembly to form a complete machine. The working principle of the frequency converter is that it can be adjusted and controlled according to the speed change of the installed equipment. There should be a complete current unit, which should be able to withstand the electric melting of a large value, as well as the equipment that can reverse change the current and the control equipment for the current value. The composition of the four parts is indispensable, otherwise there is no way to form a complete frequency converter.
The current integration unit is the foundation of sew frequency converter. What will happen here is to convert the fixed alternating current into direct current after conversion. It is the first step of current frequency conversion, and it is also a very important step. If this step is not handled well, the next links will not be completed.
High capacity electrofusion is an energy storage part, where a lot of energy is stored. It is difficult to predict what will happen in the process of current conversion. Perhaps the current will jump within one second, and there is not enough energy. At this time, the high capacitance becomes a powerful supply support to supplement electric energy. After being processed by the frequency converter, the current will also enter the capacitor through a certain channel to form a stable electric energy that can be stored for a long time. This bidirectional mutual conversion is one of the core technologies of sew frequency converter.
The difficulty of reverse frequency conversion is relatively large. It is necessary to install transistors on sew frequency converters. When they are installed on high-power machines, transistor groups are formed. DC can be changed into current of various frequencies according to different levels of switches. The amplitude of vibration and the width of generated radio waves vary widely
The controller is a key part of the whole sew frequency converter. Without its existence, even if the classification of electric frequency is meticulous, there is no way to start the machine, which is still an incomplete working system. With the controller, the work of AC motor can be better controlled.
