Source transformation in the frequency domain involves transforming a voltage source in series with an impedance to a current source in parallel with an impedance, or vice versa.
This method helps us to analyze the ac circuit with more than one independent sources.
Source TransformationAs we go from one source type to another, we must keep the following relationship below:
Note:
Can we apply source transformation on Dependent Source?
- Yes, you can apply source transformation techniques to circuits containing dependent sources, just as you would with independent sources. Source transformation is a common method used to simplify circuits by converting voltage sources to current sources or vice versa, and changing their associated resistors accordingly.
- Source transformations work for both dependent and independent sources, but the process can be a bit more complex when dealing with dependent sources, especially if their values depend on circuit variables. The general idea is to replace the original source with an equivalent source that simplifies the circuit while maintaining the same voltage and current relationships.
Let us cover the technique from the example below:
Example:
Calculate Vx in the circuit of Figure . using the method of source transformation
Solution:
We transform the voltage source to a current source and obtain the circuit in Figure. where
The parallel combination of 5 Ω resistance and (3 + j4) impedance gives
Converting the current source to a voltage source yields the circuit in Figure.
where,
