This utility model belongs to electrical equipment technical field, particularly relates to a kind of embedding Combined flat board transformer.
Background technology
Transformator is conversion alternating voltage, electric current and the device of impedance, mainly includes primary coil, secondary coil and iron core
(or magnetic core).When primary coil is connected with alternating current, iron core (or magnetic core) just produces exchange flux, makes in secondary coil
Induce voltage (or electric current).Transformator is made up of iron core (or magnetic core) and coil, and coil has two or more winding,
Wherein connecing the winding of power supply primary coil, remaining winding is secondary coil.No matter it is that coil movement passes through magnetic field or magnetic field
Move through fixed coil, all can in coil induced potential, these two kinds of situations, the value of magnetic flux is the most constant, but intersects with coil
The magnetic flux quantity of chain but has variation, and this is the principle of mutual induction.Transformator is exactly that one utilizes undesirable mutual electromagnetic inductance to answer, voltage of transformation,
Electric current and the device of impedance.
In actual use, inevitably there is copper loss (coil resistance heating), iron loss (unshakable in one's determination in transformator
Heat) and leakage field (through air close magnetic induction line) etc. problem, in order to avoid transformator temperature at work is too high, it is necessary to set

Existing transformator generally uses framing structure, relies on transformator its surface area to dispel the heat so that transformator
Volume relatively big, and radiating efficiency is limited, limits the raising of transformer efficiency.It is difficult to meet transformator on miniaturized products
Use requirement.
