Isolation Transformers and Autotransformers, Step Up, Step Down

Isolation transformers and autotransformers are devices that are used to convert the voltage of an electrical signal. Isolation transformers are designed to provide electrical isolation between the input and output circuits, while autotransformers do not provide electrical isolation. Both types of transformers use the principles of electromagnetic induction to convert the voltage of an electrical signal. Isolation transformers are commonly used in applications where it is important to prevent electrical interference between different circuits. For example, an isolation transformer can be used to connect a sensitive electronic device, such as a computer, to a potentially noisy power source, such as a generator. This can prevent electrical noise from the power source from affecting the operation of the electronic device. Autotransformers are commonly used in applications where a voltage conversion is needed, but electrical isolation is not required. For example, an autotransformer can be used to step up or step down the voltage of an electrical signal, depending on the needs of the circuit. Autotransformers are generally less expensive and more efficient than isolation transformers, but they do not provide the same level of electrical isolation.
