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.
The following types of characteristics are required in resonance capacitors which are used in the LLC capacitors of onboard chargers. Since the resonance capacitors are used in resonance circuits, it is extremely important that the capacitance change caused by temperature fluctuations is small.
A resonant circuit refers to an electrical circuit using circuit elements such as an inductor (L) and a capacitor (C) to cause resonance at a specific frequency. There are two types of resonant circuits: series resonant circuits and parallel resonant circuits.
Qseries is the Q of the series resonant circuit (i.e., Qcircuit for series), RT is the total series resistance (Rseries + Rcoil), X0 is the reactance (either XL or XC) at f0.
In a series resonant circuit, the impedance of the circuit reaches its minimum value at resonance, whereas in a parallel resonant circuit, the impedance reaches its maximum value. These characteristics are widely applied as the foundation of various electronic circuits such as in wireless communication, filter design, and signal processing.
The series resonant frequency, f0, is the frequency at which the magnitudes of the inductive and capacitive reactances are equal. This implies that the power factor is unity at resonance. Also, in a real world circuit R is the combination of the series resistance plus any resistance from the inductor's coil.
