multipower electrical components Germany multipower model multipower price

multipower electrical components are devices that convert other forms of energy into electrical energy and supply it to circuits (electronic devices). Power supplies operate on the principle of electromagnetic induction, generating electricity from renewable sources such as hydropower, wind power, tides, dam water pressure differences, and solar energy, as well as from burning coal and oil residue. A power supply is a device that provides power to electronic equipment, also known as a power supply unit; it provides the electrical energy required by all components in a computer. The magnitude of the power supply's output, and the stability of its current and voltage, directly affect the computer's operating performance and service life.

multipower electrical component principles

The working principle of a discharge tube is gas gap discharge. i When a certain voltage is applied between the two electrodes of the discharge tube, a non-uniform electric field is generated between them: under the action of this electric field, the gas inside the tube begins to ionize. When the external voltage increases to a level where the field strength between the electrodes exceeds the dielectric strength of the gas, the gap between the electrodes breaks down due to discharge, transitioning from an insulating state to a conductive state. After conduction, the voltage between the two electrodes of the discharge tube is maintained at a residual voltage level determined by the discharge arc channel. This residual voltage is generally very low, thereby protecting electronic equipment connected in parallel with the discharge tube from overvoltage damage.

multipower electrical component characteristics

The static characteristics of a sensor refer to the relationship between the output quantity and the input quantity for static input signals. Since the input and output quantities are independent of time in this case, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input quantity as the abscissa and the corresponding output quantity as the ordinate. The main parameters characterizing the static characteristics of a sensor include: linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: Refers to the degree to which the actual relationship curve between the sensor's output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted straight line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of a sensor's static characteristics. It is defined as the ratio of the increment in the output quantity to the corresponding increment in the input quantity that causes this change. Use S to denote sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide when the input quantity changes from small to large (forward stroke) and from large to small (reverse stroke). For the same magnitude of input signal, the output signals for the forward and reverse strokes of the sensor are not equal; this difference is called the hysteresis error. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor's input quantity undergoes multiple consecutive full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor's output changes over time while the input quantity remains constant. There are two main causes of drift: one is the sensor's own structural parameters; the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor's input slowly increases from a non-zero value, a measurable change in the output occurs after exceeding a certain increment; this input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor's input slowly increases from zero, a measurable change in the output occurs after reaching a certain value; this input value is called the sensor's threshold voltage.

multipower electrical component principles

A Schottky diode is a metal-semiconductor device made using a noble metal (gold, silver, aluminum, platinum, etc.) A as the anode and an N-type semiconductor B as the cathode, utilizing the rectifying properties of the barrier formed at their contact interface. Because there are a large number of electrons in the N-type semiconductor and only a very small number of free electrons in the noble metal, electrons diffuse from the high-concentration B to the low-concentration A. Obviously, there are no holes in the metal A, so there is no diffusion movement of holes from A to B. As electrons continuously diffuse from B to A, the electron concentration on the surface of B gradually decreases, disrupting surface electrical neutrality, thus forming a barrier whose electric field direction is B → A. However, under the influence of this electric field, electrons in A also produce a drift motion from A → B, thereby weakening the electric field formed by the diffusion motion. After a space charge region of a certain width is established, the electron drift motion caused by the electric field and the electron diffusion motion caused by the concentration difference reach a relative equilibrium, forming the Schottky barrier. The internal circuit structure of a typical Schottky rectifier uses an N-type semiconductor as the substrate, on which an N-epitaxial layer doped with arsenic is formed. The anode uses materials such as molybdenum or aluminum to form a barrier layer. Silicon dioxide is used to eliminate the electric field in the edge region, increasing the withstand voltage of the tube. The N-type substrate has a very small on-state resistance, and its doping concentration is 100% times higher than that of the H-layer. An N+ cathode layer is formed beneath the substrate to reduce the contact resistance of the cathode. By adjusting the structural parameters, a Schottky barrier is formed between the N-type substrate and the anode metal.
