6 FAQs about [High current modular resonant capacitor]
What is a high power resonance capacitor?
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.
Why do LLC converters need a resonance capacitor?
Therefore, the resonance capacitor requires superior characteristics. Since LLC converters have a PFM power supply which uses LC resonance, transformers and resonance capacitors are both extremely important components.
What characteristics are required in resonance capacitors?
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.
Can augmenting inductor resonantly charge/discharge all flying capacitors at different resonances?
The augmenting inductor can resonantly charge/discharge all flying capacitors at different resonances, thereby facilitating soft-charging and soft-switching operation. Based upon this concept, an 8-to-1 Multi-Resonant-Doubler (MRD) converter and a 6-to-1 Cascaded Series-Parallel (CaSP) converter are proposed and analyzed.
What is a multi-resonant switched-capacitor (SC) converter?
At 48-to-8 V conversion, the prototype achieves 99.0% peak efficiency (98.5% including gate drive loss) and 2230 W/in 3 power density. This article presents a family of resonant switched-capacitor (SC) converters with multiple operating phases, herein named “Multi-Resonant SC Converter”.
Why is the capacitance change of a resonance capacitor small?
Since the resonance capacitors are used in resonance circuits, it is extremely important that the capacitance change caused by temperature fluctuations is small. LLC converters are power supplies appropriate for use with relatively high power.
