The power IS supplied in pulses.. 60 Hz pulses. With a positive and a negative maximum each cycle. The rest of the power supply DOES smooth out the pulses, and rectifies it onto something close to DC. The ’area under the curve’ in a graphic sense is the ’power’. And thus it is maxed out twice each cycle.. Flipping to zero also twice each cycle One smart way to beef up a power supply is to INCREASE THE PULSES.. IE: boost the AC frequency. At least one power regenerator company did have a device which did this, sadly they are no longer making any product with this capability. I own a PS Audio P600 (with a optional board. now no longer available) which allows me to change the output from standard 60Hz AC up to 120Hz. I use it for my digital gear at 111Hz. .And I agree "IF" a 1 or 2 volt drop in a cord made a dramatic difference, then how to explain the variety of AC power levels, some rising and dropping every day by several volts all over the World.. No one complains?? NO outrage? (well a few folk say nights are better... |
A full-wave rectifier uses both halves ot the 60Hz input flipping the negative phase of the sine wave to create a 120Hz positive-going input to the power supply filter capacitors. * These are not square pulses with high harmonic content though. https://electronicscoach.com/full-wave-rectifier.html Darn it! I wish I knew how to post a image directly! Oh! Vacuum tube rectifiers like 5U4/ 5AR4 are full-wave. |
