round bobbin, shown in Figure 4-8, will provide the most compact design. It can be seen, in Figure 4-8, that the round bobbin provides a uniform tension, all 360 degrees around the bobbin, for both layer and random windings. The other benefit, in using a round bobbin, is the reduction and minimizing of the leakage inductance caused from the bowing.

With core parameters calculated and confirmed we now need to calculate the appropriate wire sizes. First requirement is to calculate the available bobbin width (BW A) from the actual bobbin width (BW), the number of layers for the primary winding (L) and the margin width (M). The primary winding can be 1, 2 or 3 layers, but

For transformers with power ratings less than 1 kVA, manufacturing trends tend to favor bobbin-wound coils. A bobbin-wound coil consists of layers of wire precision-wound on a rigid form. The rigid form, or bobbin, is the support platform and electrical isolation for the windings. Bobbin forms are commonly molded from thermoset materials such as

Bobbin manufacturer's catalogs are used to provide mechanical dimensions for transformer design. The bobbin manufacturers in Appendix A offer a wide variety of bobbin styles for standard ferrite core sizes in materials suitable for high volume production. Many ferrite core manufacturers also carry bobbins for their standard core sizes. PI-1907.

Primary Current = Sum of o/p Volt and o/p Amp divided by Primary Volts x efficiency. The efficiency of small transformers can deviate between 0.8 to 0.§6. A value of 0.87 works extremely well for regular transformers. The appropriate wire size needs to be determined for the winding.

Transformer/Inductor Bobbin Sizes. I have to design a 150 Ampere, 1.5 mH Inductor for a power supply project assigned to me, and off-the-shelf components are to be used. My instructor is insistent on using a transformer Bobbin to wind the conductor around, however wants me to optimize the design to standard bobbins available commercially.

P. S. Leakage inductance is a measure of how much magnetic flux couples from the primary into the secondary. The greater the distance between the primary and the secondary, the fewer flux lines there will be to couple the two windings together. Fewer flux lines coupling the windings means larger values of leakage inductance.
