Multilevel inverters with a large number of steps (more than 50 levels) can generate high quality voltage waveforms, good enough to be considered as suitable voltage template generators. Many levels or steps can follow a ...

Characterizing ultrashort laser pulses is a challenging task. By now several methods are established which can be divided into interferometric methods like SPIDER (spectral phase interferometry for direct electric field ...

A nonredundant three-stage 27-level inverter using ldquoHrdquo converters is analyzed for medium- and high-power machine drive applications. The main advantage of this converter is the optimization of levels with a minimum ...

This work proposes a methodology to generalize the Y-connections for 12- and 18-pulse autotransformers. A single mathematical expression, obtained through simple trigonometric operations, represents all the connections. ...

Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...

Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
