PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the digital wave-form can be defined either by using an adjustable analogue voltage level (in the case of a ...
PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
The power stage of switching converters can be modeled essentially as a PWM-switch. A switch seems to be far from the kind of circuit element that can be linearized, but it can be. This Part 2 ...
Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...
Hello,<P>After reading a few post from <B>stickmewithneedles</B> and <B>Unobtanium</B>, I'm planning on making a thermal fan control circuit employing PWM. <P>I've no EE degree, but I love electronics ...
voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
High current PWM controller announcements include an 80A device from International Rectifier and a 60A chip from TI. IR’s 80A programmable two-phase interleaved pulse width modulation (PWM) controller ...
Electronic systems are often subject to the power limitations imposed by their power supplies and batteries, and the maximum power available from those Jeffrey S. Mueller, Ph.D., Maxim Integrated ...
