A current sensor with PWM output is a very useful type of device. Traditionally, the device can serve in a digital application where the host microcontroller can determine the ratio of the on-time to ...

This technical document discusses a simple method of converting a PWM output signal into an analog output signal employing a Hall effect sensor or PWM sensor. This article covers the behavior of PWM ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

Texas Instruments has introduced a pair of closely-related dual-output PWM dc-dc converter controllers for space applications, one radiation-hardened and the other radiation tolerant. Both can operate ...

Use the FPGA as a CPU which allows you to add predefined I/O blocks Build custom peripherals for an external CPU from predefined I/O blocks Build custom logic circuitry from scratch Projects that ...

Graceful Shutdown: Ensuring the motor and controller are shut down safely when the application is stopped. If the application operates on a multicore MCU/DSP/FPGA, an appropriate inter-core ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...
