120V to 220V Step Up Transformer: Understanding the Basics
A 120V to 220V step up transformer is a type of electrical device that increases the voltage of an alternating current (AC) electrical supply from 120 volts to 220 volts. This transformer is commonly used in various applications, including electrical appliances, industrial machinery, and electronic devices that require higher voltage levels.
What is a Step Up Transformer?
A step up transformer is an electrical device that increases the voltage of an AC electrical supply by transferring energy from the primary coil to the secondary coil through electromagnetic induction. The primary coil, which is connected to the 120V supply, induces a magnetic field that is then transferred to the secondary coil, which is connected to the 220V load.
Working Principle of a Step Up Transformer
- The primary coil receives the 120V AC supply and induces a magnetic field.
- The magnetic field is then transferred to the secondary coil through electromagnetic induction.
- The secondary coil, which is connected to the 220V load, receives the increased voltage level.
Applications of 120V to 220V Step Up Transformers
120V to 220V step up transformers are widely used in various applications, including:

- Electrical appliances: Refrigerators, air conditioners, and washing machines that require higher voltage levels.
- Industrial machinery: Motor-driven equipment, conveyor belts, and pumps that require higher voltage levels.
- Electronic devices: Computers, televisions, and other electronic devices that require higher voltage levels.
