Step Up Vs Step Down Transformer
What is transformer and how it works.
Step up vs step down transformer. The transformer is a electric device which converts an alternating current ac of certain voltage to an ac of. A transformer is a static apparatus with no moving components. The step down transformer will cut down the output voltages. The primary difference between the two pertains to the voltage.
It transforms electrical power from one circuit to another with changes in voltage and current and no change in frequency. The turns ratio for a step. Torque reducing gear train steps torque down while stepping speed up. These two types of transformers step up and step down transformer are used to step up voltage from low value to high value according to the turns ratio of primary and secondary windings.
If n s greater than n p and v s is greater v p such a transformer in which voltage across secondary is greater than the primary voltage is called a step up transformer a step up transformer has more turns in its secondary winding than its primary winding and is used to increase the ac voltage. This transformer has less primary winding than secondary winding so we find that the current that flows through primary winding is greater than secondary winding. An electrical system cannot function without a transformer. The step up step down effect of coil turn ratios in a transformer is analogous to gear tooth ratios in mechanical gear systems transforming values of speed and torque in much the same way.
The same transformer can be used as a step up or a step down transformer. In a step up transformer the voltage input is less than the voltage output. A step down transformer on the other hand is one that the output secondary voltage is less than the input primary voltage. Step up and step down transformers are two categories of transformers categorized based on their function.
Step up transformer extends the voltages from 220v 11kv or above whereas step down transformer reduces the voltages from 440 220v 220 110v or 110 24v 20v 10vetc. This page on compares step up transformer vs step down transformer describes difference between step up transformer and step down transformer with circuit diagrams and equations.
