A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

This design idea revisits another: “PWM power DAC incorporates an LM317.” Like the earlier circuit, this one implements a power DAC by integrating an LM317 positive regulator into a mostly passive PWM ...

Explore the advantages of space vector modulation for three-phase inverters, including improved performance and reduced ...

Ebay and Amazon are awash with ‘isolated’ boards that convert pwm to 0-10V analogue, but they appear to be isolated in the sense that they an break an earth loop – great for machine control problem ...

Webasto has been granted a patent for a method to check semiconductor switch faults. By evaluating current measurements or voltage pulses based on duty cycle, faults like short circuits or open ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control ...

How to set up an PIC microcontroller to deliver high-precision frequencies from 1 Hz to 4 MHz. Examples of the frequencies delivered by this microcontroller design. In timing applications, a time-base ...

I have an NCase M1 and an open air GPU cooler so I use two fans at the bottom of the case to pull in cool air, displacing the hot air exhausted by the GPU. I'm currently using motherboard temperature ...
