3D animation explanation: The working principle of the transistor was finally shocked. Essence

In 1947, American physicist Socci, Badin and Blaton cooperated invented the transistor -a three -fulcrum semiconductor solid element. Because the transistor has the characteristics of low power consumption, small volume, relatively cheap price, flexible connection methods, etc., after the crystalline tube is released, many functions that cannot be achieved before are realized in electronic circuits, especially pulse circuits and digital circuits. Essence The following video is relatively intuitive and transparent. It is an excellent work for learning popular science. It is recommended that you see it (translated)! (Video source: Teded, Translation: @Turbo Xiaoxiao) The following animation is produced by Learnengineering, we can learn in the video very intuitively

One article understands IGBT

The full name of IGBT is insulated gate bipolar transistor, which is a compound structure device. It combines the advantages of MOS transistor and BJT bipolar transistor. It is widely used in the fields of voltage-current conversion and power output, especially in the high-voltage and high-current fields. IGBT is one of the core semiconductor devices for human beings to control and utilize power. This semiconductor device is mainly used in the field of electronic power conversion, and we collectively call it power semiconductor. The simplest applications, such as our notebook computers, are equipped with power adapters, which are IGBT, which plays a role in the process of voltage increase and decrease and AC/DC change. Obviously, IGBT is the most important member of power semiconductors. Its function is to control electricity, and it is the core chip of electric energy conversion and application.

Filter capacitance in EMC protection

Why do two 0.1UF and 0.01UF capacitors are always placed in the circuit? The two concepts of bypass and decoupling bypass capacitors and decoupling capacit are common in circuits, but it is not easy to understand. Explaining a capacitor article: The principle of animation explanation capacitance work, you can click for reference. To understand these two words, you have to return to the English context. Bypass means to copy small roads in English, and this means in the circuit, as shown in the figure below. Couple means a pair in English, extended to pairing and coupled. If the letter in the system A

IGBT module selection guidance

The selection of domestic IGBT modules should be noted at the following points: The loss of the loss of the IGBT module IGBT module is derived from the loss of the internal IGBT and diode (renewal FWD, rectifier) chip, mainly the loss caused by IGBT and FWD. IGBT is not an ideal switch, which is reflected in: (1) IGBT has saturated voltage when it is turned on -VCESAT (2) IGBT has switching energy consumption when switching -EON and EOFF. This is the source of IGBT loss. VCESAT causes the informal loss, and EON and EOFF causes switching loss. Direction loss + switch loss u003d IGBT total loss. FWD also has two aspects of loss, because::

SIC-MOSFET chip technology development

1. Introduce the development of semiconductor chip technology to enable power devices to effectively use electrical energy, such as crystal gates and diode, which plays a key role in voltage and current control. Relative to the currently widely used SI semiconductor chip, wide -band semiconductor SIC chip can improve the performance of the product and reduce losses. SIC materials have good physical characteristics. Compared with traditional devices, SIC devices can reduce loss by 50-70%and work at a higher frequency. The use of SIC devices in the system can reduce the power loss of the product, and can also reduce the volume of the cooling system and passive components.

Switching power ring circuit response (Berdu) test

The oscilloscope is the most important power test and representation tool. At present, many oscilloscope can provide a dedicated power measurement option to help engineers automatically complete many important tests, such as the German technology Infiniivision X series oscilloscope. The power supply not only needs to measure the time domain, but also the measurement of the frequency domain is also crucial. The frequency response measurement includes the control ring response (Bodetu) and the power suppression ratio (PSRR). Such specific incentive response measurements are usually completed by low -frequency network analyzers, but some new oscilloscope built -in functions/arbitrary waveform generators, so it can also be used for such measurements. Let ’s introduce the corresponding test of the switching power supply circuit. Control ring response (Bernu) Power supply is actually a negative
