Description

one

And the 3 rd definition relates to the P | reoperator of the 1m frequency of changes 1NO: 1n1cr and it can use: use, for example, in automation, -BbH measurement and measurement technology.

Doublers are known for allowing the output of a device to be produced at a device and a sinusoidal voltage of 1J, 2.

However, the known ycTipoHCTiBa have an insignificant excitation range for the input voltage, a sharp decrease in the output voltage with an increase in the input voltage, a large amount of: mO (Current and cores.

Closest to the invention is a device containing a magnetic module with primary O; b circuits, connected in series and 0 to connect a primary circuit and a secondary one: & a capacitor and a linear inductor with a capacitor and a secondary circuit of the i2J.

The purpose of the invention is to expand the operating range of the excitation and simplify the device.

This is achieved by the fact that an additional capacitor is connected in series with the primary circuit and a diode is connected in series with the secondary winding.

FIG. 1 is a diagram of the proposed device; on f | ig. 2 is a diagram of voltage changes.

Stabilized a1vtopa, meter: ICheko frequency doubler consists of a capacitor cl, a three-rod magitoprovod with obmoshami (Wi and Wi - primary, W -

secondary, and the primary windings have the same number of turns), Ca coadensor, linear induction1ННО | СТ1И LZ and diode D.

The primary windings Wi and Wj, located on the extreme rods of the magnetowire,

interconnected in such a way that the magnetic flux created by these windings is closed along K regional wires. At the middle rod there is a secondary Wj connected at one end to diode D, to which is connected with one clip a chain consisting of parallel-connected condenser C and linear inductive; one hundred L, the other terminal of which is connected to the second end of the SECONDARY ROUND.

The proposed frequency doubler operates in the mode of auto excitation: a parameter of metric oscillations. The excitation of auto-parametric oscillations of the doubled frequency in the secondary circuit of the doubler occurs softly and is maintained steadily in a wide range of variation of the input voltage L / i (Fig. 2). A constant magnetic field is created by a constant component of the current flowing through the winding with the number of turns Wz. This field

occurs at the same time with the excitation of auto-parametric oscillations in the secondary circuit. As a result of a strong automatic subwave, as well as a selection of LZ and Cr parameters, such that the actual resistance for the second harmonic cable is more large than for the rest of the MOI11, more straightforward, the current pair will change to the real-time mode, as a rule, the practice and the practice will become a good practice. alshy

The doubler voltage at the output (/ 2 (Fig. 2)) practically does not depend on the | Mening and voltage L / i at the input, i.e., the doubler works as a voltage stabilizer doubled 4iaiCTOTbi. The stabilization effect reaches 11 due to a | rvic1No.go.control C, W / and Wi, which is a ferroresonion chain, in which the deposition at the terminals of the primary windings changes slightly with a significant change in the input t /.

At the same time, the stabilization of the output load Uz is more effective than in a simple ferroresonance circuit, since the stabilization of the excited output voltage

a third of the higher harmonic voltage on the primary o6iMOTOiK clamps significantly affects.
