Working Principle of Electronic Transformers An electronic transformer is essentially an unregulated switching power supply based on inverter technology. The operating process begins by rectifying AC input voltage into DC voltage. After that, electronic switching components generate a high-frequency oscillation that converts the DC power into high-frequency AC power. This high-frequency energy is then transferred through a high frequency transformer, which changes the voltage to the required output level. Finally, the output may be rectified again depending on the application requirements. This process allows electronic transformers to achieve high conversion efficiency and stable performance. Compared with traditional transformers, a high frequency power transformer operates with much smaller magnetic components because high-frequency operation reduces the required core size. As a result, the entire system becomes more compact and lightweight. The high frequency transfor...
