As engineers, you use many components and devicesevery day that you treat as black boxes. You are concernedonly about the inputs and outputs of the blackbox, and that approach is acceptable provided ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

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 ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...

This circuit drives a resistive heater element with a low-frequency, pulse-width modulation (PWM) voltage source, providing heat output that's directly and linearly proportional to the duty cycle of ...

Sprayer operators keen to get turn compensation without switching to pulse width modulation now have the option of a system that works with conventional twin or quad nozzle bodies. Smart C Spray 124 ...

Why PWM? Switch-mode converters employ a power semiconductor switch (usually a MOSFET) to drive a magnetic element (transformer or inductor) whose rectified output produces a dc voltage. Efficiencies ...
