Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Resized, sorry dont have time to get on computer, just posting from phone, lemme know if you can make those out.

Yes, that is better!

Same setup using half bridge tho, you see the current rise in 10% and work done the other 90.

You need to take the duty cycle and means into account when  calculating average power, peak powers don't compare.

AlteredUnity

Duty cycle is about 8%, mean voltage = 60v, mean current = 36mA for last pic, duty is 10% and mean values shown on scope.  Unless im missing something?

alan

15v x 0.06a = 0.9w only for continuous DC. At Tdc = 10%, 10% of the period is 0.9w, 90% is 0w, 100% period is 0.09w average (Ppeak x Tdc/Tperiod), because you want to know power over continuous time, not per period or peak.
