Power Frequency Transformer

Power-frequency transformers are based on Faraday's law of electromagnetic induction. Input power-frequency AC current generates an alternating magnetic field in the primary coil, which couples to the secondary coil through the core's magnetic circuit, inducing a voltage. Their size and weight increase significantly with power (due to the fixed frequency, the core cross-sectional area must be larger). Efficiency is typically 95%-99%, with no-load losses primarily due to core eddy currents and hysteresis losses.

Product Details

Features

◆Simple and reliable structure: It consists only of iron core (silicon steel sheet) and copper/aluminum winding, without any electronic components;

◆Strong electrical isolation: The primary and secondary sides are coupled through magnetic fields to achieve physical electrical isolation, which is highly safe.

◆High stability and lifespan: no high-frequency switching loss, strong resistance to voltage shock, and low maintenance cost;

◆Low-cost advantage: The manufacturing process is mature and the material cost is lower than that of high-frequency transformers.
