An electronic transformer is a type of power conversion device that takes an AC input of 220V and converts it to a lower AC output of 12V. It can handle power levels ranging from 50W to 300W. This kind of transformer is based on a high-frequency electronic ballast circuit, offering better stability, compact size, and higher power output compared to traditional silicon steel core transformers, which are often bulky, heavy, and more expensive. Essentially, an electronic transformer functions as an unregulated switching power supply. It works by first converting the incoming AC into DC through rectification. Then, electronic components generate a high-frequency AC signal, which is transformed to the desired voltage level via a switching transformer. Finally, the output is rectified again and used to power the connected device. Due to its small size, light weight, and cost-effectiveness, this technology is widely used in various electronic appliances today. Depending on how the high-frequency switch transistor is driven, electronic transformers can be classified into two main types: self-oscillating and externally excited. Each type has its own advantages and is suited for different applications. The self-oscillating type generates its own frequency, while the externally excited type requires an external signal source to trigger the oscillation. This distinction plays a key role in determining the performance and efficiency of the transformer in specific use cases.
