The voltage stabilizer diode is made of the voltage stabilizer performance shown by the reverse breakdown characteristics of PN junction, also known as Zener diode or reverse breakdown diode, which plays a role of voltage stabilizer in the circuit. It uses diode reverse breakdown, in a certain range of reverse current,……

At present, electric vehicles are basically one of the indispensable means of transportation for every family, and the safe driving of electric vehicles is also very important. With the development of science and technology, all kinds of electric vehicles and accessories have adopted new safety monitoring technology, e……

When a current flows through a semiconductor in a magnetic field, it generates a voltage (hall voltage) in a direction at right angles to the current. This phenomenon is known as the Hall effect. Hall element is a magnetic detection element using hall effect. Hall elements are made from InSb (indium antimonide) and GaA……

What are the advantages of two IGBT modules in parallel over one IGBT? There are several reasons for using IGBT in parallel: First, demand reduces cost. Taking Dianping as an example, although the product stability can be improved by directly purchasing finished modules from Semikong and other manufacturers, the corres……

IGBT power module is driven by IC, various drive protection circuits, high-performance IGBT chip and new packaging technology. It has developed from composite power module PIM to intelligent power module IPM, power electronics building block PEBB and power module IPEM. PIM is developing in the direction of high voltage……

Reversely connected. Its function is not only rectifier, but also the rapid connection or cutting of the non -contact switch, realizing the inverter of the DC power into AC power, turning the AC electricity of one frequency into another frequency AC power, and so on. Like other semiconductor devices, it has the advanta……

Why can't SIC devices replace IGBT? The production process and technologies of silicon carbide (SIC) devices are becoming increasingly mature. The biggest obstacle to marketing is the cost. Including research and development and production costs, and the cost of driving capacitance resistance in the entire circuit afte……

What are the commonly used IGBT buffer circuits? Because the electrical electronic devices have four working status: ON, ON, Turbus, and OFF, the OFF and ON status are supported by high voltage and large current respectively. Streaming, excessive DI/DT, DU/DT and excessive instantaneous power. Therefore, in order to pr……

How to use a multimeter to detect thyristor with thyristor of thyristor, one -way thyristor and two -way thyristor, all have three electrodes. One -way thyristor rectifier has cathode (K), anode (A), control pole (G). Two -way thyristor is equivalent to two single -thyroid reverse parallel parallel. That is, one unidir……

The semiconductor triode parameter symbol and its significance If the total current seductive coefficient β \\u003d IC/IB \\u003d 100 is emitted, the collector current IC \\u003d β*IB \\u003d 10mA. When the collector load resistance is 500Ω, the voltage drops VRC \\u003d 10mA*500Ω \\u003d 5V, and the voltage drop betwe……

Precautions for module selection-Direction angle requires that the module outputs a large current when the module (that is, the module high input voltage, low output voltage) output, which will cause the module to be severely heated or even burned. This is because the current value measured with a normal instrument und……

Three main reasons for thyristor breakdown 1. Overdrawing: Over -crushing breakdown is one of the main reasons for thyristor breakdown. The thyristor has almost no time to withstand the voltage, even if the voltage is performed within a few milliseconds. Therefore, in the actual application circuit, the ends of the sil……
