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 ...

Texas Instruments Incorporated introduced an off-line green mode pulse width modulation (PWM) controller that minimizes space and system cost while providing high efficiency in power supply ...

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 ...

In previous posts, I have introduced several do-it-yourself pwm controller circuits and reviewed several Chinese PWM controller modules. The next step in this post is to share the design of another ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

The company has increased the speed of its 2026A 2.05-GHz. signal generator's pulse modulator to 15 nanoseconds. By replacing the pulse modulator in the unit, the speed of the pulse modulation rise ...

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...
