 | PWM - Pulse Width Modulation w/ Variable Frequency There will be more videos to come soon. I have really been wanting to replicate what Tortuga0303 did in his vid "Energy Propagation." Also, to those interested in PWM for HHO purposes, I have read the patent of Henry K. Puharich "Method and Apparatus for Splitting Water Molecules".......www.google.com it seems that he ended up using a sawtooth wave form at about ~3400 htz to vibrate the molecules apart. Stan Meyer probably did the same. Anyway, my hope is that someone tries that because I won't be able to for a while. Here is the schematic for the Variable Frequency PWM......www.hhocarfuelcell.com 2010年06月13日再生回数 1598 |

 | PWM - Pulse Width Modulation PWM is used in many systems for power control and this explains briefly how it works, using a MOSFET step down converter and a table lamp (see related video). Microcontrollers often provide PWM outputs and most switching supplies use PWM principles. By switching at a high frequency rather than linear control the efficiency is very high. PWM is sometimes called Duty Ratio Modulation. 2010年02月24日再生回数 4682 |
