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.
In choosing coupling capacitors for audio frequency work, aluminum electrolytics or tantalum capacitors may be a good option. Niobium electrolytic capacitors may suit low-voltage applications (10 volts or less) with safety concerns. Higher voltage applications and operation at higher frequency may require Class 2 ceramic capacitors.
Class 1 (NPO/COG) ceramic capacitors and silver mica capacitors are often used in resonant circuits. In single-phase motor applications, capacitors with values above 70 µF are starting capacitors. Run capacitors (typically 3 to 70 µF) are designed for continuous duty and are energized the entire time the motor is running.

To determine which one is the best fit for your application, let’s first look at the basic structure of each capacitor type. SLCs are the most basic capacitor type available since these capacitors consist of a single layer of dielectric material, or insulating layer, sandwiched between a positive and a negative electrode.

Get PriceNear self-resonant frequency, inductive reactance cancels the capacitive reactance. Why do capacitors block DC but pass AC at high frequencies? Answer: With DC, frequency is zero, so reactance is infinite, blocking current. With high AC frequencies, reactance nears zero, allowing current to pass. How does frequency affect capacitor impedance? Answer: As frequency …
