Electric welding equipment is a device that uses electrical energy to generate heat to weld metal parts together. In the past, welding power sources used large and heavy metal transformers. Their operating frequency is 50 or 60 Hz, and their efficiency is relatively low. The development and wide app

1. Foreword Aluminum electrolytic capacitors are the most critical component that restricts the service life of the inverter. The main reason is the service life of aluminum electrolytic capacitors, especially in high-harmonic current and high-temperature applications such as inverters. Compared wit

Film capacitors are electronic components, which are used in many household appliances and have a wide range of applications. Film capacitors are electronic components made of metal foil, polypropylene, polystyrene, and other materials. With many advantages and superior performance, it is now the ma

Capacitor is a very important electronic component in the circuit, so we must pay attention to protect it when using it, and extend its service life as much as possible. Fortunately, when we buy, we can test the withstand voltage and leakage current, and do not miss any tiny places. These tests can

The film capacitor itself is generally not easy to be broken. It seems that there is no direct connection with the IGBT, but the actual impact is great:1. Clutter promotes high-load operation of IGBT, which increases heat generation and affects the life of IGBT2. If the DC-LINK film capacitor is not

The reason why film capacitors can be widely used and used by major manufacturers is that film capacitors have self-healing capabilities. There are two different mechanisms for the self-healing of film capacitors: one is discharge self-healing; the other is electrochemical self-healing. Discharge se

Film capacitors have many excellent characteristics, such as non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and low dielectric loss. It is widely used in analog circuits. The current operation of film capacitors is regular. When using film ca

In new energy, what are the advantages of film capacitors compared to aluminum electrolytic capacitors? 1. Aluminum electrolytic capacitors are liquid capacitors with short service life. Many users of solar and wind energy products require more than 15 years of product life, that is, the products mu

Film capacitors are widely used in home appliances such as air conditioners, fans, washing machines, and can also be used in the transportation industry. They are very important electronic components. 1. The role of film capacitorsWhen film capacitors are used in electronic circuits, film capacitors
