  • How do pull up pull down resistors affect PWM signals in motor control . . .
    Some participants express confusion about the connection between pull up pull down resistors and PWM signals, particularly in how they influence voltage levels and transitions One participant notes that pull up down resistors are not used in the H-bridge power circuit but may be relevant in the PWM signal control circuits
  • Duty Cycle and Frequency of PWM: Explained - Physics Forums
    The discussion revolves around the concepts of duty cycle and frequency in pulse-width modulation (PWM) Participants seek clarification on how these two concepts relate to each other, with a focus on their definitions and implications in practical applications Some participants assert that duty cycle is the ratio of "on time" to "off time" during one period and argue that it is not related
  • Can You Run PWM Fan Without PWM Input? - Physics Forums
    Excuse my lack of knowledge on PWM and fans, but can a fan configured with 4 wires (power, ground, tach signal, and PWM input) be run off of a DC power supply without using the PWM to control its speed? As in, not using the PWM lead and just hooking up power ground and controlling fan speed

    Some participants discuss the possibility of inverting the PWM signal to achieve a higher duty cycle There is mention of using a 556 timer, which is two 555 timers in one package, as a potential solution
  • PWM wat is het, hoe gebruik ik het met mijn fan en waterpomp
    Na het lezen van wat veel gebruikers doen hier op GOT en op andere sites, zag ik dat veel mensen nog niet door hebben wat PWM voor hun kan betekenen om de PC's (water) koelers aan te sturen, want PWM is wat dat betreft echt een game changer Daar de meeste niet door hebben wat men met een PWM pomp of PWM fan kan doen, en hoe het werkt Index Wat is PWM? Hoe werkt het? Wat zijn de voor en
  • Kühlmittelpumpe für Ladeluftkühlung: Kein Signal - P190C00
