1 PrefaceThe modern induction heat treatment technology is widely used because of its high quality, high efficiency, and environmental protection. As the basis of induction heat treatment technology, the IGBT module of the inverter has been commercialized and has successfully produced 10 ~ 100 kHz IGBT inverter power supply with hundreds of kilowatts of power. Practice has proved that the use of IGBT variable-frequency power

. Generally, after more than a dozen cycles, the voltage at both ends of the energy storage filter capacitor can be charged to the maximum value. For example, if the electrical inductance of the transformer secondary coil is 10-1000, and the capacity of the energy storage filter capacitor is 10000-1592, the following formula can be obtained: ω =, or F = Hz, T = 628 microseconds, 1/4 cycle is 157 microseconds; set the switching power supply to 40 kHz,

I have talked about the principle of variable frequency power supply before, but many users and enterprises still do not know it, and do not pay much attention to the normal maintenance and maintenance of Variable Frequency Power Supply in Hong Kong. When using the Frequency Conversion Power Supply in different seasons, the single-phase and Three-Phase Frequency

U disk is also required to power, if the power supply is not normal use, or the computer can not correctly identify. About the U disk because of power supply cause can not use also have many kinds of situations, some friends are desktop can not use, some are notebooks, some may be the reason for USB interface, below we will answer for everyone. 1, the desktop U disk power

1. Overview of three types of non-isolated DC-DC topologies 1.1Buck type converter The buck converter topology is shown in Figure 2.2 and the buck Converter is also known as a buck-type power supply topology. When the switching tube s is on, the diode VD negative voltage is higher than the positive reverse cutoff, at which time the current is fed through the inductance L to the capacitance and load, while the inductance L stores the energy. When the

June 30, 2015 – NetSuite, a leading provider of cloud-based finance/ERP software, today announced that it is committed to improving the sound input quality of smartphones, tablets and other mobile devices, and that the silicon microphone manufacturing industry is the leader Since the use of NetSuite cloud ERP, Akustic, a wholly-owned subsidiary of the Bosch Group, has significantly improved the efficiency of its supply chain across all regions. Based

The filter capacitor can also be called the DC capacitor, which is one of the important components in the inverter power supply. It has a unique role in it. In the future, we will be able to better understand the frequency conversion power supply. So let's talk about the role of the filter capacitor in the inverter power supply. What is the function of the filter

Overview: The entire structure of an automobile is complex, with tens of thousands of parts. However, the basic structure of an automobile can be divided into four parts: Engine, chassis, body, and automotive electronics. The proportion of automotive electronics to total vehicle costs has been rising. Currently, automotive electronics accounts for 15%-30% of total vehicle costs. For some high-end vehicles, automotive electronics accounts for nearly 40%-50% of total costs. With the continuous dev

Human resources Obtaining method: outsourcing, outsourcing, and leasing. The significance of supply management: With the progress of society, the position of supply chain management becomes more and more important. As the project organization bec

When buying a computer, you are too concerned about the speed of the CPU, the memory capacity, the speed, and the hard disk capacity and speed, this is also the most transparent, and the majority of businesses are most willing to publicize and boast to use. However, we all ignore a very important issue. The power supply of the PC is the foundation for other components to work normally and stably for a long time. If you don't have a good power
