Apologies

Hi This is a really trivial comment in my notes but for some reason I'm not seeing it... The following image demonstrates the perpendicular distance from an origin to the line of action of the force given as x*sin(x,F). So the moment, M = f*x*sin(x,F) which I understand. But why is it...

Thank you for your post, I shall have a good look at this.

Hi guys I'm looking to make an induction heater to heat bits of steel and aluminium (maybe 15mm by 25mm). Can anyone recommend a good source of information in terms of calculating the various parameters and other general information? I've looked at many websites but a lot of them seem to...

Ah ok. So then I need to multiply by the square root of 2. I also need to take away 2v for the diodes and then 0.5v for the average of the ripple? I think you're right about the integration by the way.

The two levels would be 11.5 and 12.5v, right? I haven't integrated this stuff before but I'll try and follow the advice and see what happens!

Vo sounds like the ripple voltage still though. I guess that's wrong though?

Any help on the power please?

Sorry that must have been a typo. It's 30 degrees. There is a voltage drop of 1v across each diode, so 2v.

Something like this?

Hi Thanks for the replies. I think I'm to take the 12V as RMS and the current is the current through the load (average I guess??). I also think it's 30 degrees of 180. So for the power, its the dt of the I = c(dv/dt) I'm trying to find? In which case this would be dv = dt*(I/c)... v =...

Hi guys I'm working on a few questions regarding the full wave rectifier circuit similar to the attached image. The AC voltage is 12v at 110Hz, the ripple voltage is 1v peak to peak and the load current is 24mA. I am to assume each diode has a forward voltage drop of 1v when conducting...

Thanks for your reply, that's helpful. So in the case of a function generator etc, how would you know what the limits of the circuit were, such as max curren they could handle? Would that be the input perameters?

Hi I'm just thinking over a few things and realized there's something pretty fundamental that doesn't seem to get explained often or at least very well. Maybe I'm too much of a novice, who knows...anyway... When a power supply states a power output of say, 750W, what exactly does that...

Ahh right ok I see. That makes sense. Ha, it does seem so much straight forward now I'm further down the line. Thank you so much for your help. I'm sure you can see I would have never in a million years worked all this out myself. You guys and this forum are great!
