How does the Step-up Transformer Work

Step up transformer is a machine which can start the voltage instantaneously. At present, there are few domestic transformer manufacturers who can effectively boost the voltage instantaneously. The step-up transformer has a strong ability to boost voltage instantaneously and has a good boost effect. The difference lies in that the non-excitation voltage regulating switch does not have the ability to change gears with load, because this kind of tap changer has a short-term breaking process in the process of shifting gears. Breaking off the load current will cause arcing between contacts to burn the tap changer or short circuit, so the transformer must be cut off during gear adjustment. Therefore, it is generally used for the transformer whose voltage requirement is not very strict and does not need to be adjusted frequently.


The Working Principle of Step-up Transformer

The step-up transformer is a device which can transform low AC voltage, large current and small impedance into high AC voltage, small current and large impedance. When there is AC current in the primary line, AC magnetic flux will be generated in the iron core (or magnetic core) to induce voltage (or current) in the secondary coil. The input of transformer must be AC power supply, whose output voltage is directly proportional to the turn ratio of the output or input coil. If you use a battery, because it is DC, you must add a switch circuit in the input circuit to change it into a constantly changing voltage. In this way, alternating high voltage can be obtained at the output end.
