<p>The present invention relates to a transformer with a pass core for preventing the core from being excessively saturated between a primary coil and a secondary coil, wherein the primary coil is formed in an E-type core and the secondary coil is formed on the upper side of the primary coil with a predetermined interval. A second pass core penetrated to pass an air current is stacked on the vertical one or both sides of the pass core which is formed between the primary coil and the secondary coil. Therefore, heat transmitted to the core and the pass core is blocked or a temperature is reduced by cooling the heat by passing the air current through the second pass core by the pass core-stacked transformer.</p> |
