MMG India Pvt Limited offers Economical Transformer Design -ETD Cores. MMG India Pvt Limited is an ISO - 9002 certified company. Economical Transformer Design - ETD Cores were developed specifically for Power Transformer cores used in Switched Mode power supplies. The combined cross-sectional area of the two outer limbs equals the cross-sectional area of the centre limb allowing an even flux distribution throughout the core. This ensures the absence of localised `hot spots` that can reduce performance at high frequencies or high flux levels. Their round centre limb provides for minimal winding resistance, leakage inductance and copper eddy current losses. Economical Transformer Design - ETD Cores are available in a range of sizes and materials together with their associated coil formers [both Horizontal and Vertical mounting] and clips.
