On July 26, it was reported that Fuji Electric will increase the production capacity of a new generation of power semiconductors in 2024 to about 10 times that of 2020. Recently, it was reported that in order to cope with the growing demand for silicon carbide power semiconductors in the fields of pure electric vehicles (EVs), Fuji Electric plans to launch a new ...

The frequency conversion speed regulation function of the inverter (hereinafter referred to as -VFD) is to convert the three-phase power frequency (50Hz) AC power supply (or any power supply) into a three-phase AC power supply with adjustable voltage and frequency. Frequency conversion speed control device can also be sometimes called VVVF, which is mainly used to adjust AC motors (asynchronous or synchronous machines).

Fuji Electric Corporation (President: Tsuhiro Kitazawa, Head Office: Shinagawa-ku, Tokyo) is pleased to announce that it has completed a major upgrade of its FRENIC-MEGA series of general-purpose inverters in order to improve power at its production sites. ※Echo characteristics: output signal ...

An electric energy control device is used in many industries, which can play a good role in energy saving. In the process of using the inverter, there will be noise and vibration problems, so what are the causes of these problems? And how to deal with it? Below the small ...

On June 26, the "2019 South China Fuji Electric System Products Intelligent Manufacturing Technology Exchange Conference" jointly sponsored by Fuji Electric (China) Co., Ltd., China Transmission Network and China Motion Control Industry Alliance was held in the boutique exhibition area of China Motion Control Industry Alliance at the South China Automation Exhibition (Shenzhen Convention and Exhibition).

The annual Shanghai Tourism Festival is here as scheduled. The theme of this year's festival is "Meet the Belt and Road", which aims to strengthen tourism exchanges and cooperation with countries and regions along the Silk Road Economic Belt and the 21st Century Maritime Silk Road. Under this theme, we find this year in all 23 ...

Fuji Electric inverter has many precautions during use. Here are some methods to learn. 　　The ambient temperature has a great influence on the service life of the inverter. For every 10°C, the service life of the inverter will be halved, so the ambient temperature and inverter dissipation must be solved.

Ultrasonic level gauge is a non-contact instrument that uses the principle of echo ranging. The echo ranging principle is also known as the travel time or travel time measurement principle. It emits energy waves through a device that can emit energy waves (generally pulse signals), and the energy waves are reflected when they encounter obstacles, and are reflected by a ...

In order to solve the problems of inaccurate metering and billing, difficult collection of water charges, and serious waste of water resources in agricultural irrigation water, modern automatic control, radio frequency triggering and other technologies are used to achieve the goal of paying the fee before using water, charging according to the quantity, automatic metering, and automatic opening and closing of the pump.

Because the waters are intersected and connected, the waste discharged by each country and region is concentrated in the deep sea, and marine garbage has long become a global problem. Most of the marine debris is concentrated in five untouched areas, each of which falls in the Pacific Ocean of China, which is larger than the ...

Fujifilm ultrasonic flowmeter is a non-contact flowmeter that has only been applied with the rapid development of integrated circuit technology in the past ten years, which is suitable for measuring fluids that are not easy to contact and observe, as well as large pipe diameter flows. Together with the water level gauge, it forms an open channel flow meter for flow measurement of open water ...

Following the last release of the circuit breaker Q&A, we have received new circuit breaker inquiries one after another, and this time we have selected the questions about the "protection function" with a high interest rate for answers: (1) What exactly is a "protection function"? (2) How should I look at the "action characteristic curve"? (3) When selecting, facing ...

1. The working principle of Fujifilm ultrasonic flowmeter A complete set of Fujifilm ultrasonic flowmeter is composed of ultrasonic generator, ultrasonic receiver, electronic circuit, flow display, accumulation system and other structures. The principle of ultrasonic flowmeter is shown in Figure 1. As you can see from Figure 1, ...

Since the advent of automatic induction motors, variable frequency operation has existed in the form of alternators. Change the rotational speed of the generator, and change its output frequency. Before the advent of high-speed transistors, this was one of the main ways to change the speed of the motor, but due to the generator speed ...

The source of AC converter interference comes from interference from the external power grid. Harmonic interference in the power grid mainly interferes with the frequency converter through the power supply of the frequency converter. There are a large number of harmonic sources in the power grid, such as various rectifier equipment, AC and DC interchange equipment, electronic voltage adjustment equipment, nonlinear loads and lighting equipment.

In order to achieve a more efficient and controllable operation of the motor, and avoid the waste of power of the motor drive system, the inverter came into being. However, due to the variety of motor load types, the functional requirements for the equipped inverter are also different, so how to choose the right transformer for the motor...

The people are the foundation of the country, the valley is the life of the people, diligence and thrift are the fine traditions of the Chinese nation, and food security is an important foundation for national security. At present, the security situation at home and abroad is complex, and the sudden outbreak of the epidemic has caused multiple challenges to global food security. October 16, 20201 is World Food Day.

The cause of the leakage problem We all know that the three-phase stator winding of the motor flows through the current to produce a rotating magnetic field, according to the principle of magnetoelectric induction, the shell of the motor will produce an induced electromotive force, the size of this electromotive force depends on the size of the switching frequency of the inverter IGBT, due to the high ...
