Motor and motor control technology is the core technology of new energy vehicles. In the process of motor control, DC support capacitor is needed to provide instantaneous energy. With the development of film capacitor technology, especially the development of base film technology and the emergence of metallization segmentation technology, not only the volume of film capacitor is smaller, but also the withstand voltage level of products is larger. More and more companies use high-temperature polypropylene film capacitor as DC support capacitor. At present, most of the domestic and foreign companies are using high-temperature polypropylene film capacitor as DC support capacitor Thin film capacitors are used as DC support capacitors in current brand new energy vehicles. For example, the filter capacitor used by the first generation Toyota Prius is electrolytic capacitor. Since the second generation, thin film filter capacitor has been used. In addition to the application in motor drive controller of new energy vehicles, thin film capacitors have been widely used in many fields, such as automotive air conditioning, household appliances, industrial control, military industry and so on.
Technical advantages of thin film capacitors
1. The product has good safety and strong over-voltage resistance
2. Good temperature characteristics, wide application range of product temperature, - 40 ℃ - 105 ℃
3. Stable frequency characteristic, good high frequency characteristic
4. No polarity, can withstand reverse voltage
5. High rated voltage, no need of series and balance resistance
6. Low ESR and strong ripple current resistance
7. Low ESL
8. Strong ability of anti surge current
9. Long service life
