How do you determine the optimal capacitor energies?

SSL output impedance (scaled by switching frequency as it does not effectthe minimizatio ) and the second t i C2 λ (vc,i(rated))22i∂L 1= (vc,i(rated))2Ci − Etot , the optimal capacitor energies are proportional to th product of theirrated voltage and their charge mul

How can a decoupling capacitor avoid via starvation?

Avoid via starvation by determining maximum current carrying capacity and numbers of transitional via. The loop inductance is a parameter quantifying the effectiveness of a decoupling capacitor. Figure 6 represents the different loop inductances added to the capacitor ESL. Figure 7 shows a typical flow for capacitors Z-parameters extraction.

How do you calculate C capacitor loss?

c capacitor’s loss can be related to its voltage swing during a period. During each period, the capacitor is charged and discharge between voltages 1 and v2, to charge levels q1 and q2, respectively, as during a single period corresponds to:Ecap = ∆v · ∆q = C∆v2,(11)where the second equa ity in equatio is equal to

How many capacitors does a doubling stage use?

Each stage doubles the voltage and uses two capacitors and fourswitches. The last doubling stage only uses one capacitor, as the output capaci or is that stage’s secondcapacitor and is ignored in this omputation. For can :n2(2k − 1)2RSSL1 =8Etotfsw(77)(3n2 − 4n)2RSSL2 =4Ctotfsw(78)Each switch in a sing e stage su any switch

What are the design guidelines for switch-capacitor converters?

development of design guidelines forswitched-capacitor (SC) converters In particular, the output impedance formulas given in equations (10) and(15) en ble the optimization of t e size of each individual capacitor and switch. These optimizations allowfor the better utilization of capa inv

How do capacitors compensate for parasitic loss?

portional to switch area and thus areproportional to switch conductanc . To compensate for parasitic loss, the capacitors must b made larger toallow for a lower switching freq ency and parasitic loss. If the FSL impedance was made lower inste oss would increase as the switch conductances increase.5 Control Methods
