A proper capacitance value is selected based on the frequency and amplitude of the signal in the circuit.” Talk about voltage rating.
WPT is a good example of opportunities for resonant coupled converters. C0G MLCC has better capacitance stability than any other type of capacitors ! LLC converter uses the PFM (pulse frequency modulation) method, which controls the switching frequency while maintaining a fixed pulse width.
When selecting a resonant capacitor, refer to the allowable voltage graph and allowable current graph on each product page in the Product Center, and consider the configuration of the capacitor bank so that both the voltage and current applied to the capacitor do not exceed the allowable voltage and current.
