TAKE NOTE
i'm happy to continue discussing other member's attempts ... to replicate the results i'm getting

Hi NP
Hope you dont mind me posting this here,but it is in regards to some flyback testing i have been doing on a coil for another project.

I am not sure whether RMS or average values are used to calculate power in this case?.
Maybe void could shed some light on this

Brad

i suggest you go and dump your testing results from "another" project onto a thread started by Void, where he's sharing with us all an OU-related project he's made...

there must be plenty of those, right?

I know you dont like input from those that know,such as void,as it doesn't agree with your mistakes.

I just thought you might like something with substance on your thread,as you seem to be here all alone now  .

But you enjoy your journey of solitude.

Hi NP
Hope you dont mind me posting this here,but it is in regards to some flyback testing i have been doing on a coil for another project.

This coil differs from most,as it has a PM for the core,and is giving some very interesting results.

The measurements taken below do not include the power dissipated by the LED,but only the power flowing into C1 from the source,and then the power flowing out of C1 into the coil.

The calculated power from C1 is only calculating the power delivered by C1 to the coil when the transistor switches on-->duty cycle is 5%.
This is far greater than the power being delivered to C1 by the source.

So there is more power flowing through the coil,than there is being delivered by the source.
This means that the magnetic field being built by the coil is far greater than that that could be built by the supplied power from the source. And as i stated above,this is not including the power being dissipated by the LED.

I am not sure whether RMS or average values are used to calculate power in this case?.
Maybe void could shed some light on this.

Hi Brad. Average power is calculated using RMS values for the voltage and current,
however it is not that straightforward. Coils and capacitors produce reactive currents
which are out of phase with the voltage across them. This is sometimes referred to as
'reactive power' but it is not really power. When you are looking at efficiency of circuits
you are only concerned with real power, which is power consumption that depletes energy in
a power source, or power consumption in a load that consumes power, such as resistors
and bulbs. Power calculations for the purpose of determining circuit efficiency applies
to the input power from your power source and the output power for real power consuming loads.
Looking at current flowing in coils and capacitors does not tell you about the efficiency of
the circuit. That is an interesting setup with the coil around a magnet core however.
All the best...

awwww, that's so SWEEEEEET, it's almost like you really cared about me being lonely!

how could i possibly be lonely when i have you here, Big Boy?!?

i don't care what the others say about you, you'll always have a special place in this thread now


...let's close the door quietly  now and give these two lovers some privacy
