Most of us know about PWM DACs. They are easy to implement, cheap, and acceptable for low performance applications. The approach is to filter the HF components of the PWM signal and be left with only ...

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 ...

The question that arises in the design of a simple PWM DAC is what the low-pass filter pole frequency should be relative to the PWM frequency. This question is addressed by deriving the design ...

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 ...

This solution is said to combine a PWM controller IC with the 700V and 800V CoolMOS P7 MOSFETs in a single package, designed to support isolated and non-isolated flyback topologies. According to ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

Precise configuration is simple with a convenient USB connection to a PC. Other features include an operating temperature range of -40 to 80 °C (32-176 ºF), electrical noise immunity, and surge ...
