Enter the wafer factory and learn more about the chip manufacturing process

Some transistors are more than 50 billion, and these transistors are 10,000 times smaller than human hair. They are made on the huge super -clean cleaning plant floor, which can reach seven floors height, and the length is equivalent to four football fields. Micro -chip is the lifeblood of the modern economy in many aspects. They provide motivation for computers, smartphones, cars, electrical appliances and many other electronic products. But since the epidemic, the world's demand for them has surged, which has also led to interruption of supply chain and global shortage. This in turn exacerbates inflation and caused people's alertness in the United States: the United States is becoming too dependent on overseas chips. The United States only accounts for about 12%of global semiconductor manufacturing capacity.

Analysis | Shallow Mainland Electric Drive System EMR4

1. Forewords With the significant acceleration of electric vehicles in the market, the differences between brands, market segments and models are also increasing, and the maximum expansion of the applicability of the electric drive system is more important. Electric -driven systems, such as large -scale EMR3 (third -generation electric drive system) and EMR4 currently developed, are designed at the system level. Compared with the previous generation, EMR4 has improved by up to 5%efficiency, significantly improved power scalability, and greatly reduced costs. Improve efficiency and performance is the technical route and direction proposed by the vehicle to the electric drive system. In order to promote the improvement of EMR4 performance, many chains that affect the efficiency and performance of electrical drive have been

Various losses inside the switching power supply

To improve the efficiency of the switching power supply in the main loss of the switching power supply, it is necessary to distinguish and roughly estimate the various losses. The loss inside the switching power can be roughly divided into four aspects: switching loss, conducting loss, additional loss and resistance loss. These losses usually appear at the same time in damaged components, and they will be discussed separately. The loss power switch related to the power switch is one of the two most important sources of loss within the typical switching power supply. Losses can basically be divided into two parts: divertal loss and switch loss. Direction loss is when the power device has been opened and the driver and switch waveforms have been stable, the power switch is in the duration of the power switch; the switch

Driver technology of the new energy vehicle motor controller IGBT module

This article introduces the design ideas of the motor controller IGBT module driving circuit, explains the characteristics of the IGBT module, the design and protection of the gate -drive circuit, and the current, voltage, and temperature protection of the IGBT module in normal operation. And provide corresponding design principles and verification schemes. 1. Introduction IGBT (Insulated Gate Bipolar Transistor), the insulated grid bipolar transistor is a composite full -control voltage drive power semiconductor device composed of BJT (bipolar triode) and MOS (insulating grid field effect tube). There are two advantages of high input impedance of MOSFET and the low -conducting voltage drops of GTR. IGBT

Boost booster circuit principle and design detailed explanation

The Boost circuit is a type of switch DC voltage voltage, which can make the output voltage higher than the input voltage. It is a more common circuit design in electronic circuit design. This article will introduce the basic principles and circuit parameter design to you. First of all, we need to know: capacitors hinder the change of voltage, pass high frequency, block low frequency, communicate, and block DC; inductors hinder current changes, low frequency, high frequency, direct flow, blocking flow;
