At resonsance, the impedance approches infinity (this of course is impossible... there are always circuit paracitics).
From the WWW...
The solution to the circuit (which is a second order differential equation) is
i(t) = Ae ^+ jωt + Be ^− jωt
Considering the initial conditions, solve for A...
The term "ground" is often not used properly. You'll hear things like... connect it between +5V and ground... this is not correct, it should be connect it between +5V and 5V return. Power supplies are not referenced to ground, they are referenced to their return. Now it maybe that the return is...
That is not a easy question to answer unless your familiar with... transfer functions, the complex frequency domain and what bode plots are, and what they tell you.
The short answer is... the output capacitance and load resistor form a pole at a frequency of
Unfortunatly the "twisted pair" concept (and it's benefits) have been around decades prior to the internet showing it's face. I doubt the laws of physics have changed, but
there just might be something there.
Hey... as soon as you made the line "dedicated" you got bandwidth, but on the flip...
It also relates to the reverse recovery time... in the case of a switching diode, Trr is "fast".
Besides rectifier diodes, and general purpose diodes, there's the Schottky, no Trr, a lower forward voltage, but a much higher junction capacitance.
You have to remember all wires and circuit traces have inductance ~20nH/inch. If you need to supply large amounts of current fast, the voltage will dip. Many components (active) can't tolerate dip's below certain levels, so a "local current source", in the form of a capacitor, is added.
Pull-up...
It depends on the topology that you are using... if the primary is push-pull, then the drain voltages on the MOSFET's will be 2x Vin plus any spikes from cross conduction or leakage inductance. How high these spike will be is hard to say, there are many factors to consider.
The "clamp" that...
I don't think the properties of copper wire have changed since 88, but what about the method by which the information is sent? I would have to think great strides have taken place in that arena over the past 20 years, no?
Technically, all switch mode converters require a load (especially converters that run in the continuous conduction mode). Voltage mode converters are even worse in regards to min load levels because of the right halfplane zero in the transfer function.
Specifically for a Cuk, I don't know...
