Wrong.

There can be no equivalent transformation between ideal voltage source and ideal current source;

The actual power supply can be simulated as an ideal voltage source and internal resistance in series, or an ideal current source and internal resistance in parallel. These two forms can be converted equivalently.

Ideal power supply: it is abstracted from the original power supply. When the power loss of the power supply itself can be ignored and only its function of generating electric energy can be represented by an ideal active component. There are two kinds of voltage sources and current sources.

Ideal voltage source: it is an ideal power supply, which can provide a constant voltage with constant magnitude and direction for the circuit, but it is not affected by the load, and the voltage at its two ends is not affected by the load. The symbol of the ideal voltage source and its volt-ampere characteristic curve are as follows:

Ideal current source: it is an ideal power supply, which can provide constant current with constant magnitude and direction for the circuit, but it is not affected by the load. The voltage across it depends on the constant current and the load. The symbol of the ideal voltage flow and its volt-ampere characteristic curve are as follows:

From the definition of ideal voltage source and ideal current source, the voltage across the ideal voltage source is not affected by load, while the voltage across the ideal current source depends on current and load. It can be seen that the two are completely opposite and cannot be equal to each other.

The actual power supply can be simulated as an ideal voltage source and internal resistance in series, or an ideal current source and internal resistance in parallel. The two forms of the same actual power supply reflect the same external characteristics, and the two forms can be equivalently transformed.

The conditions for equivalent conversion of two actual power supply models are as follows (refer to the above figure).

note:

During equivalent transformation, the magnitude and direction of the voltage and current of the external circuit remain unchanged.

Equivalent transformation is equivalent to an external circuit, not an internal power supply.
