Advantages of an autotransformer:
1. Cost-effective: Autotransformers are generally more cost-effective than traditional transformers because they require fewer materials and are more compact in size.
2. Efficient: Autotransformers are more efficient than traditional transformers because they have lower losses and higher voltage regulation.
3. Compact size: Autotransformers are smaller and lighter than traditional transformers, making them easier to install and transport.
4. Voltage adjustment: Autotransformers can be used to adjust voltage levels, making them versatile for a variety of applications.
Disadvantages of an autotransformer:
1. Single winding: Autotransformers have a single winding, which means that the primary and secondary windings are not electrically isolated. This can be a safety concern in certain applications.
2. Limited isolation: Because the primary and secondary windings are not fully isolated, autotransformers may not provide the same level of protection against electrical faults as traditional transformers.
3. Limited voltage ratio: Autotransformers have a limited voltage ratio range compared to traditional transformers, which may limit their use in certain applications.
4. Potential for voltage spikes: Autotransformers can produce voltage spikes during operation, which may damage sensitive equipment connected to them.

Advantages:
- Reduced copper losses: Autotransformers utilize the existing voltage of the supply line, resulting in lower current draw and reduced copper losses compared to traditional transformers.
- Smaller size and weight: Autotransformers have a compact design due to the sharing of one winding, making them more suitable for space-constrained applications.
- Lower cost: The simpler construction and reduced amount of copper required for autotransformers result in a lower overall cost compared to isolation transformers.
- Voltage regulation: Autotransformers can provide voltage regulation by adjusting the number of turns in the common winding, reducing voltage fluctuations and improving power quality.
- Continuous adjustment: Autotransformers offer the advantage of continuous voltage adjustment, allowing for precise control of the output voltage within a specific range.
Disadvantages:
- Electrical isolation: Autotransformers do not provide electrical isolation between the primary and secondary circuits, which can be a safety concern in some applications where isolation is required.
- Voltage surges: In certain conditions, such as sudden load changes or faults, autotransformers can experience voltage surges that can damage connected equipment.
- Harmonics: Autotransformers can generate谐波失真 due to the nonlinear nature of their windings, which may interfere with other electronic devices connected to the same power line.
- Limited voltage range: The voltage conversion range of autotransformers is limited, as they rely on the existing voltage of the supply line. They may not be suitable for applications where a wide range of voltage conversion is required.
- Potential for circulating currents: If the autotransformer is connected to a system with a floating neutral, circulating currents can flow through the common winding, leading to increased losses and overheating.
- Reduced copper losses: Autotransformers utilize the existing voltage of the supply line, resulting in lower current draw and reduced copper losses compared to traditional transformers.
