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.
High Voltage Film Capacitors: Polypropylene film capacitors have advantages such as high voltage breakdown strength, a wide voltage range (50 to >10,000 Vdc), very low loss, and a low Dissipation Factor (DF). They also have high ripple current capability and are suitable for AC or DC applications with ripple. The designs can be dry or impregnated.
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.
