High voltage inverter film capacitor

4 FAQs about [High voltage inverter film capacitor]

Are film capacitors good for inverters?

For the performance needed for inverters, film capacitors are often adopted to meet the demand for high voltage endurance, long life, and high reliability. Up to this point, the superiority of film capacitors has been introduced, but they are not superior in all characteristics. One of such characteristic is the capacitance per unit volume.

What is the demand for film capacitors?

The demand for inverters used in environment-related equipment such as EVs/HEVs and solar/wind power generation systems is expanding in the capacitor market. For such applications requiring enduring high voltage exceeding 500 VDC and long-term use for several tens of years along with a high level of safety, demand for film capacitors is increasing.

Are film capacitors a good choice for inverter power bridges?

Moreover, modern film capacitors not only perform better but can be a cost effective technology as well if applied correctly. inductance in an inverter power bridge leads to inefficiencies due to the voltage spikes they produce when the power devices are switched on and off at a high rate of dI/dt.

What are general-purpose film capacitors made of?

General-purpose film capacitors are often made with PP. As you all know, environment-related markets, including inverters used in EVs/HEVs and solar/wind power generation systems are largely expanding. In particular, demand for high-power applications (high voltage exceeding 500 VDC, large capacity) is increasing.
