Definitions
- one of these functions is to increase the output voltage by acting on the current flowing in a tertiary winding and to regulate it as a function of this current.
- the invention relates to a self-induction electric transformer, comprising at least two closed magnetic circuits (4 and 5) connected and at least three windings (1, 2 and 3), a winding (1) of which the core is the exposed part of the first magnetic circuit (4), a winding (2) whose core is the connecting part of the two magnetic circuits (4 and 5) and a winding (3) whose core is the exposed part of the second magnetic circuit (5) .
- the magnetic circuits (4 and 5) in connection separate from each other at the end of the connection part, and that on both sides of the linked part, to form the released part.
- the ends of the open part of the same magnetic circuit are oriented towards each other before entering the connecting part to form a closed circuit.
- the ends of the magnetic circuits linked on one side tend to have the same direction before entering the linked part.
- a magnetic circuit can have several linked parts and each part can contain several linked magnetic circuits.
- the magnetic flux generated by the flow of electric current in the winding surrounding the open part exits from one end and enters the other end of the same magnetic circuit, passing through the connecting part of the linked magnetic circuits, without reaching the rest linked magnetic circuits.
- the magnetic flux generated by the flow of electric current in the winding surrounding the connecting part is distributed over the magnetic circuits of which it surrounds the part in connection, and it circulates only in the magnetic circuits of which it surrounds the part in connection and the parts in connection of the neighboring magnetic circuits in the case where these magnetic circuits have several parts in connection .
- the present invention is a reversible self-induction electric transformer, the role of the primary (l) of which can alternate between the primary (1) and the tertiary (3) or a winding of the free part of a magnetic circuit in case of having more than two magnetic circuits and the function of the secondary (2) will be realized by the windings which surrounds the part in connection of the magnetic circuits.
- figure 1 shows the case of an auto-induction electric transformer with two magnetic circuits and three windings only, it is an example, the application of this invention is not limited to this example .
- the present invention can be used as an electrical transformer with an output voltage regulated across the secondary (2) as a function of the current supplied by the tertiary (3), its operating principle is as follows:
- the secondary winding (2) of the connecting part operates as an armature, when one of the primary windings (1) surrounding the exposed part of one of the magnetic circuits is an inductor.
- the secondary winding (2) of the connecting part functions as an armature and an inductor at the same time, when it delivers a current, it induces a voltage at the terminals of the tertiary winding (3) surrounding the part free from the other magnetic circuit.
- the power balance of the present invention according to application is:
- the input power is the power absorbed by the primary (1)
- the output power is the sum of the powers supplied by the secondary (2) and the tertiary (3) independently in the case of two magnetic circuits, in the case of having more than two magnetic circuits by simply adding the powers of the other windings those of secondary (2) and tertiary (3).
