The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...
The ISL78223 is a high-performance zero-voltage switching(ZVS) full-bridge PWM controller. It achieves ZVS operation by driving the upper bridge FETs at a fixed 50% duty cycle while the lower bridge ...
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 ...
Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: (1) The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy ...
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 ...
The microprocessor allows for custom programming to fit specific OEM requirements, potentially eliminating the need for a PLC and supporting devices. Drives can be easily programmed for use in the ...
Applications ranging from consumer electronics to high-power energy-conversion systems leverage the benefits of dc-dc power converters in their designs. Among these, flyback converters are popular for ...
Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...
