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 ...

We propose a novel flexible jitter-enhanced pulse width modulation(PWM) hardware architecture, which aims to improve the modulation resolution while reducing the requirement of PWM frequency. The ...

Presented here is a PWM amplifier circuit (Figure 1) built around a two quadrant driver circuit that can amplify 3.3V or 5V signals to a higher level. Figure 1 PWM amplifier circuit built around a two ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

The most prevalent reason for IGBT failure in voltage-source inverter (VSI) is thermal stress, which is influenced by the topology and modulation technique adopted. Hence, it is crucial to understand ...

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 ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...
