ENERGIE electrical components Germany ENERGIE model ENERGIE price

ENERGIE electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from a light source into a modulator via an optical fiber. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is introduced via the optical fiber, passes through the modulator, and is then emitted, where the function of the optical fiber is first to transmit the light beam, and second to act as an optical modulator.

ENERGIE electrical component characteristics

Typically, the actual static characteristic output of a sensor is a curve rather than a straight line. In practical applications, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximate the actual characteristic curve. Linearity (non-linear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero input and full-scale output points can be used as the fitted line; or the theoretical straight line that minimizes the sum of squared deviations from each point on the characteristic curve can be used, known as the least squares fitted line.

ENERGIE electrical component principle

The main raw material for ferrite beads is ferrite. Ferrite is a ferrimagnetic material with a cubic lattice structure. Ferrite materials are iron-magnesium alloys or iron-nickel alloys; their manufacturing process and mechanical properties are similar to ceramics, and their color is gray-black. One type of magnetic core frequently used in electromagnetic interference (EMI) filters is ferrite material, and many manufacturers offer ferrite materials specifically for EMI suppression. This material is characterized by very high losses at high frequencies and high permeability, which minimizes the capacitance generated between the coil windings of an inductor under high-frequency, high-impedance conditions. For ferrites used in EMI suppression, the most important performance parameters are permeability μ and saturation flux density Bs. Permeability μ can be expressed as a complex number, where the real part constitutes inductance and the imaginary part represents loss, which increases with frequency. Therefore, its equivalent circuit is a series circuit composed of inductance L and resistance R, where both L and R are functions of frequency. When a wire passes through this ferrite core, the resulting inductive impedance formally increases with frequency, but the mechanism differs completely at different frequencies. In the low-frequency range, the impedance consists of the inductive reactance of the inductor. At low frequencies, R is very small, and the core's permeability is high, resulting in large inductance; L plays the major role, and EMI is suppressed by reflection. At this stage, the core loss is small, and the entire device acts as an inductor with low loss and high Q characteristics. Such inductors are prone to resonance, so in the low-frequency range, using ferrite beads may sometimes result in increased interference. In the high-frequency range, the impedance consists of the resistive component. As frequency increases, the core's permeability decreases, leading to a reduction in inductance and inductive reactance. However, core loss increases, and the resistive component increases, leading to an overall increase in impedance. When high-frequency signals pass through the ferrite, EMI is absorbed and dissipated as heat. Ferrite suppression components are widely used on printed circuit boards (PCBs), power lines, and data lines. For example, adding ferrite suppression components at the power line entry point of a PCB can filter out high-frequency interference. Ferrite rings or beads are specifically designed to suppress high-frequency and spike interference on signal and power lines, and they also have the ability to absorb electrostatic discharge (ESD) pulse interference. The value of two components is proportional to the length of the bead, and the length of the bead has a significant impact on suppression effectiveness; the longer the bead, the better the suppression. For power filtering, inductors can be used. The circuit symbol for a ferrite bead is that of an inductor, but the model number indicates that a ferrite bead is used. In terms of circuit function, ferrite beads and inductors operate on the same principle, differing only in their frequency characteristics. Ferrite beads are composed of oxide magnets. Ferrite beads provide significant impedance only to high-frequency signals; at low frequencies, their resistance is much lower than that of inductors. Ferrite beads are a rapidly developing anti-interference component that is inexpensive, easy to use, and highly effective at filtering high-frequency noise.

ENERGIE electrical component structure

Commonly used are unidirectional thyristors, also known as ordinary thyristors. They are composed of four layers of semiconductor material, have three PN junctions, and have three external electrodes: the electrode drawn from the first layer of P type semiconductor is called the anode A; the electrode drawn from the third layer of P type semiconductor is called the gate G; and the electrode drawn from the fourth layer of N type semiconductor is called the cathode K. As seen from the circuit symbol of the thyristor, it is a unidirectional conductive device like a diode, but with the addition of a gate G, giving it operating characteristics completely different from those of a diode. The P1N1P2N2 four-layer, three-terminal device, based on silicon single crystal, is internationally known as the silicon controlled rectifier, abbreviated as thyristor T, because its characteristics are similar to those of a vacuum thyratron. Since thyristors were initially used in static rectification, they are also called silicon controlled rectifiers, abbreviated as SCR SCR. In terms of performance, SCRs not only have unidirectional conductivity but also possess controllability more valuable than that of silicon rectifier elements (commonly known as "dead silicon"). They have only two states: conduction and cutoff. SCRs can control high-power electromechanical equipment with milliampere-level currents. If this power is exceeded, the switching loss of the component increases significantly, and the allowable average current decreases; in this case, the nominal current should be derated. SCRs have many advantages, such as controlling high power with low power, with power amplification factors reaching hundreds of thousands of times; extremely fast response, turning on and off within microseconds; contactless operation, no sparks, no noise; high efficiency, low cost, etc. Weaknesses of SCRs include poor static and dynamic overload capacity and susceptibility to mis-triggering due to interference. SCRs are mainly classified by appearance into bolt-type, flat-type, and flat-base types. Structure of SCR components. Regardless of the shape of the SCR, their die consists of four layers of P1N1P2N2 structure composed of P type silicon and N type silicon. It has three PN junctions (J1, J2, J3). The anode A is drawn from the P1 layer of the J1 structure, the cathode K is drawn from the N2 layer, and the gate G is drawn from the P12 layer, making it a four-layer, three-terminal semiconductor device.
