Simplified network transformer

A network transformer, comprising:

• an iron core body comprising a first winding section, a second winding section, a first flange and a second flange on both ends of the iron core body, and a third flange situated between the first flange and the second flange, where the first winding section is positioned between the first flange and the third flange, while the second winding section is located between the second flange and the third flange;
• the first flange has a first electrode set comprising a first electrode, a second electrode, a third electrode, and a fourth electrode;
• the second flange has a second electrode set comprising a fifth electrode and a sixth electrode;
• the third flange has a third electrode set comprising a seventh electrode, an eighth electrode, a ninth electrode, and a tenth electrode;
• a first winding assembly comprising a first coil and a second coil, where both ends of the first coil and the second coil are electrically connected to the first electrode set and are wound around the first winding section;
• a second winding assembly comprising a third coil and a fourth coil, where both ends of the third coil and the fourth coil are electrically connected to the third electrode set and are wound around the first winding section;
• and
• a third winding assembly comprising a fifth coil and a sixth coil, where both ends of the fifth coil and the sixth coil are electrically connected to the second electrode set and the third electrode set, and are wound around the second winding section.
