Description

Inductor for damping function in system circuit

The present invention relates to an inductor for damping function in a system circuit, which can amplify the electric energy when the system has a positive damping effect, and can eliminate the eddy current when the negative damping effect is performed, so that the power waveform is not easily distorted.

1 shows a conventional inductor 1 comprising: an iron core 10; and a coil 11 wound around the core 10. The iron core 10 is mostly made of manganese zinc or nickel zinc. The reactance of inductor 1 shown in Figure 1 is X _L = 2π f L, which has only a basic inductive effect. When the frequency of the power in the system circuit is too high, the inductor 1 will form a wire in an instant without inductive action. When high-powered electric energy flows through the inductor 1, the temperature of the inductor 1 rises and energy is consumed.

2 shows a conventional semiconductor inductor 2 comprising: a ring-shaped amorphous germanium semiconductor core 12 and a wire passing through the central via 121 of the amorphous germanium core 12 13. The semiconductor inductor 2 is mostly used in a system circuit for converting electric power into electric energy, and the magnetic energy amplification effect can amplify the current or voltage of the power outputted from the power output end, thereby improving the electric energy gain. The semiconductor inductor 2 shown in FIG. 2 can generate a high-frequency magnetoresistive inductor and is suitable for use in a system circuit for transferring high-frequency, high-power electric energy. When high-frequency, high-power electric power flows through the semiconductor inductor 2, high heat is generated, and the temperature of the semiconductor inductor 2 is increased to consume energy. In practice, the semiconductor inductor 2 must be placed in a coolant (insulating oil) to reduce the semiconductor power. The temperature of the sensor 2 can maintain normal operation.

The present invention provides an inductor capable of generating a damping function in a system circuit, comprising: an amorphous germanium semiconductor magnetic core enclosing a magnetic circuit, a permanent magnet coupled to the semiconductor magnetic core, and the semiconductor magnetic core Used with the wire. The permanent magnet is directly adsorbed on the semiconductor magnetic core and integrated with the semiconductor magnetic core. The semiconductor magnetic core can generate a high frequency magnetoresistive inductor whose inductance increases as the frequency of the electrical energy increases. The permanent magnet can produce a negative inductance whose inductance decreases as the frequency of the electrical energy increases.

The amorphous germanium semiconductor magnetic core is annular and has a through hole in the center. The wire is through a central through hole of the semiconductor core.

A wire of the inductor is wound around the semiconductor core.

The permanent magnet has a magnetic strength of 5,000 gauss or more.

The inductor can amplify electrical energy when used for positive damping effects, and can eliminate eddy currents when used for negative damping effects.

The reactance of the inductor generates an oscillating action, which eliminates eddy currents and does not cause an energy increase in temperature rise.
