This article explains the difference between a voltage amplifier and stepup transformer. Manufacturers of stepup transformer India will acknowledge readers about the features of these two products.
Stepup transformer is designed for increasing the magnitude of primary voltage applied, which increases the amplitude of voltage wave form. A voltage amplifier does the same thing. If both the products perform same function, then how can these two products be different from each other? This question comes in people’s mind after reading the above statement. Well, there are major dissimilarities between a stepup transformer and a voltage amplifier and we will discuss them now.
Amplification
Stepup Transformer – these equipments are unable to amplify an AC input voltage without lowering its capacity of current.
Amplifier- An amplifier is different than stepup transformer because it can amplify both voltage and current at the same time.
Direct Current Voltage Requirement
Transformer – There is no need of DC voltage to operate the transformer’s coil windings. At times, a DC voltage might be there in a transformer winding for auxiliaries, but the direct current never needed for the transformer operation.
Amplifier- An amplifier is different than stepup transformer because it can amplify both voltage and current at the same time.
Voltage Amplification
Transformer- It has more numbers of windings added to its secondary winding to acquire voltage amplification.
Amplifier- Amplifier modulates a fixed direct current source voltage in response to an AC input voltage to acquire output voltage amplification.
Input Current
Transformer- The input current of the transformer is proportional to its load current.
Amplifier- Input current of the amplifier is usually almost independent of its load current.
Design
Transformer – Transformer is like a gearbox that converts energy.
Amplifier – Amplifier is like an engine that requires fuel to provide output. It consumes DC supply to provide output.
Flexibility
Transformer – stepup transformer has ability to amplify a specified input type and add to that the range of input. Transformer is usually very flexible in range.
Amplifier- Amplifier has ability to amplify any signal. It would have a limited range.
Output Impedance
Transformer – In ideal design of transformer, output impedance is = the source impedance X the square of the turns ration.
Amplifier – Output impedance of the amplifier is independent of the source impedance.
These are the perfect reasons to explain why stepup transformer cannot be similar to amplifier. Exporters of stepup transformer India have explained the difference between these two products at best.
