A PWM circuit works by making a square wave with a variable on-to-off ratio; the average ‘on’ time may be varied from zero to 100%. In this manner, a variable amount of power is transferred to the ...

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 ...

This idea was created to solve a design problem we faced a few months ago. The circuit we were working on was used to steer an H-bridge that was controlled by a TMS320F2810 digital signal processor ...

Spice model makes it easy to design with PWM amplifiersHigh-efficiency PWM amplifiers are displacing linear designs in many applications. You can design a constant-current or a constant-voltage PWM ...

The most common type of power supply today is the switching supply. The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output.

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude Pulse width modulation is a form of signal ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

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 ...

Fractal Design will begin distributing the Aspect RGB PWM White Frame series of daisy chain-compatible rifle bearing fans. The "Aspect" series of case fans by Fractal Design, which launched last year.

While you have been able to read our review, the press release was still pending. Fractal Design revealed a new take on one of their most popular new case designs with the Define S2 Vision, a ...
