Isolation Transformer is a type of transformer that is used to isolate or separate electrical circuits while allowing the transfer of power between them. It provides galvanic isolation, which means there is no direct electrical connection between the input and output sides of the transformer. Instead, the transformer uses magnetic coupling to transfer energy from the primary winding (input side) to the secondary winding (output side).

Here are some key features and purposes of isolation transformers:

1. Galvanic Isolation: The primary purpose of an isolation transformer is to provide electrical isolation between the input and output circuits. This prevents the flow of direct current (DC) and blocks common mode noise between the two sides.
2. Voltage Level Conversion: Isolation transformers can also be used to convert voltage levels. For example, if you have a device that requires a different voltage than what’s available in your power supply, an isolation transformer can step up or step down the voltage accordingly.
3. Noise Reduction: Isolation transformers help to suppress electrical noise, interference, and voltage spikes. This can be especially important in sensitive electronic equipment to ensure proper functioning and prevent damage.
