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 ...

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 ...

Intelligent digital controllers can simplify power-supply design as well as enhance overall reliability through monitoring and statistical interpretation of key performance metrics. Multiple methods ...

Geneva—STMicroelectronics has extended its portfolio of power management devices with a family of flexible and high-performance PWM (Pulse Width Modulation) controllers intended for motherboard and ...

This application note presents BLDC motor control using sensor sinusoidal PWM modulation with Z32F128 microcontroller. It also discusses ways on how to implement sinusoidal PWM modulation and ...

A Dutch-designed pulse-width modulation (PWM) system for sprayers claims greater flexibility and application quality compared with other options on the market. On traditional crop sprayers, the only ...
