High-power resonance capacitors are an important component in magnetic resonance using wireless power transfer EV charging systems. This is because a high-accuracy resonance circuit with high withstand voltage is required for quick, efficient wireless transfer of a large amount of power.
Dry plastic-dielectric (film) capacitors provide high-reliability and low-loss characteristics suitable for power electronics applications. These capacitors feature a tight capacitance shift versus temperature and frequency, lightweight, no oil or electrolyte, and flexible packaging options.
Decreasing capacitor ESL and increasing resonant frequency allow the capacitors to operate over a higher bandwidth. The capacitor designs must account for conductor heating resulting from the insufficient cross-sectional conducting area due to skin depth at high frequency.
These capacitors feature a tight capacitance shift versus temperature and frequency, lightweight, no oil or electrolyte, and flexible packaging options. They are efficient and cost-effective, and metalized film capacitors offer self-healing leading to soft failure modes over a long service life.
Film capacitors are particularly well suited to high power applications in low to medium voltage markets. Applications in power electronics include voltage transient snubbing, coupling and decoupling, DC links, feed-through, EMI line filters, and inverter AC output filters.
The resonant capacitor is one of the most important parts of the system due to high effective current that it has to conduct. This paper presents experimental results obtained during the selection of the most adequate capacitor technology for the resonant capacitor. 1. Introduction

Capacitor Selection for Hi-Rel CLLLC LLC LCC Resonant Converters
11. Select the Resonant Capacitor The resonant capacitor (Cr) must have a low dissipation factor (DF) due to its high-frequency, high-magnitude current. Capacitors such as electrolytic and multilayer X7R ceramic types usually have high DF and therefore are not preferred. NP0 capacitors can be used due to their low DF, but their capacitance range

Capacitor Selection for high frequency resonant circuits
5kHz is no longer fast for many ''lytics (polymer types particularly), films rated for 600V won''t protest if operated at 6V, and increasing frequency by a decimal place or two will likely require the question to be revisited all over again, not leastwise because many devices sold as capacitors are actually inductors at higher frequencies.
