A Revolution in Transformer Design and Manufacture

Superior Performance

The performance of the Jencore is such that full retention of the magnetic properties of the parent material is possible.

This is because:

• the exciting field is in parallel with the strip
• the Distributed Gap Jencore effectively has no gaps, and
• the steel suffers no more degradation after annealing.

The performance of this core enables the designer to run his transformer at peak "revs" i.e. at 1.8 Tesla. However, 1.7 Tesla is preferred for normal design with over-voltage requirements.

Typically, a Jencore in M5 material will have a loss of 1.24 W / kg at 1.7 Tesla 50Hz or 0.73 W / lb. at 1.7 Tesla 60Hz. In other words, the graphs given by the steel manufacturers can be used for the results obtained by an annealed Jencore.

Tesla	W/kg Annealed
1.5	0.8
1.6	0.99
1.7	1.18
1.8	1.5
1.9	2.22

NOTE: Material used was an M5 grade with the test certificate reading 1.20W17/50.

In certain cases, where annealing is too costly or unobtainable, one can design without it. By adding 10% more cross-section to the Jencore, one can achieve the same results as that of the annealed core.

This graph shows the comparisons between various Jencore styles and conventional C Cores and Toroids. A series of cores of identical mean magnetic path length were produced under controlled conditions from the same coil.

• Uncut Jencores overlay conventional Toroidal cores.
• Distributed Gap Jencores are very close to Toroidal cores in characteristics.
• Zip Butt Jencores are better than Step Butt Jencores and conventional C Cores in characteristics.

Therefore, the Jencore is the most efficient core available today and offers users very high-energy savings at a low price. This makes the Jencore ideal for Distribution Transformers, Solar Inverters and Uninterruptable Power Supplies.
