Power isolation analysis of medical devices

The power isolation analysis of the medical equipment is increasingly closely close to the diagnosis and treatment of modern medical equipment. Any medical equipment is inseparable from a safe and stable power supply, and most of them are switching power supply. Whether a medical equipment can exert its maximum effectiveness, in addition to the direct relationship with the technical performance of the machine itself, it also has an extremely important relationship with the quality of power supply power. The quality of the power supply will directly affect the operational stability and reliability of medical equipment. Products with non -standard quality of power supply may lead to major medical equipment accidents and huge economic losses. Safety u0026 isolation is a major commercial power supply and medical power supply

Talk about the power supply system and power driver of new energy vehicles

With the development of human society, there are more and more demand for energy. Energy use based on traditional methods, in addition to bringing more convenient lifestyle to humans, also brings a series of environmental pollution and climate warming. Negative impact. This prompted people to turn their attention from underground to the sky, seek the use of solar energy to replace fossil energy, realize the renewable cycle of energy, and finally achieve the ultimate goal of carbon neutrality. The electrification and electrification of the automotive power system are the only way to achieve carbon neutrality in the field of transportation. As the world's number one automotive semiconductor technology company, Yingfei Ling is convinced of the view of "zero emissions will be realized" and is committed to Promote the early realization of this goal.

Buck converter's PCB layout and design

1. Buck converter key circuit and key nodes no matter what type of converter, the key to the design of the PCB layout is to find the key circuit and key nodes of the circuit system. So what is the key loop and key node of the circuit system? Generally, the current change rate DI/DT large loop and voltage change rate DV/DT large nodes are key circuits and key nodes. When designing the PCB layout, priority and layout should be given priority. When the buck converter is opened and cut off, the current and waveforms of each ring road are shown in Figure 1. (A) The current circuit opened by the upper management (B) The current circuit of the upper tube is cut off (C) L1 and L2

IGBT chip technology detailed explanation: why is it called the "core technology" in the field of electric vehicles

The types of chips are diverse. Today I will introduce a chip IGBT, which is closely related to our lives (INSULED -Gate Bipolar Transistor), which is closely related to our lives. This chip is extremely widely used on electric vehicles. IGBT is a chip controlled by an AC electric motor output control for electric vehicles, railway locomotives, and EMUs. IGBT directly controls the conversion of direct and AC power, which determines the torque of the drive system and the maximum output power. Therefore, how can your car accelerate, how much speed, and energy efficiency look at it. IGBT accounts for about half of the cost of the motor drive system, accounting for 5 % of the cost of the entire vehicle, and the cost of the entire electric vehicle

My country's silicon carbide industry chain!

The silicon carbide (SIC) material is the main progress direction of the power semiconductor industry. It is used to make power devices, which can significantly improve the power utilization rate. In the foreseeable future, new energy vehicles are the main application scenarios of silicon carbide power devices. As a pioneer of technology, Tesla has taken the lead in integrating all -line silicon carbide modules in Model 3, and other first -tier car companies also plan to expand the application of silicon carbide. With the increasing reduction in the cost of silicon carbide devices and the gradual maturity of process technology, the silicon carbide power device industry is expected in the future. [What is silicon carbide?] Silicon carbide (SIC) is the third -generation compound semiconductor material. The cornerstone of the semiconductor industry is a chip. The core materials of making chips are divided into the historical process: the first generation of semiconductor materials (mostly high -purity silicon currently widely used

What are the 100 rankings in China IC design?

Aspencore released the "Chinese IC Design 100 Rankings" at the China IC Leadership Summit in 2021, showing the Chinese semiconductor industry people with 100 best IC design companies. We divide the companies on the list into 10 categories, select TOP 10 from about 30 companies in each category, and finally form a "100 rankings in China IC Design". Below we interpret the screening standards and reasons for the selection of these 100 companies. The listed company (PUBLIC) TOP 10 listed companies rank in accordance with the "Comprehensive Power Index". The comprehensive strength index is determined by the following three factors: 1.2020 fiscal revenue (weight 0.5)

Another idea of single -chip computer program firmware encryption

With the emergence and development of large -scale integrated circuits, the single -chip microcomputer (MCU) integrates the CPU, RAM, ROM, timer, and multiple I/O interfaces on the original computer to a chip -level computer. This is also the prototype of the world's first micro controller (MCU)-TMS 1000 series (below) invented by Gary Boone and Michael Cochran of TI engineers. Later, Japanese electronic manufacturers began to produce car -controlled cars, including 4 -bit MCUs used for in -car entertainment, automatic wiper, electronic locks and dashboards, and 8 -bit MCUs for engine control. * TI's TMS 1000 series MCU* time to time
