Fast, high‐current pulse generator with variable amplitude and width

Fast, high-current pulse generator with variable amplitude and width

a one-dimensional random walk, for which the statistical properties are well known. The essential idea behind this approach can best be seen in Eq. (2) where the individual t; + r terms in the sum on the left represent steps in a unidirectional random walk, the walk being terminated when the value Tis reached. A detailed treatment (facilitated by the definition of the I; given above) shows that...

Power Quality Analysis for Modular Structured Multilevel Inverter with Bipolar Variable Amplitude Multicarrier Pulse Width Modulation Techniques

MultiLevel Inverter (MLI) is used in applications that need high voltage and high current especially for Flexible AC Transmission System (FACTS) controllers. The topologies of multilevel inverter have several advantages such as lower Total Harmonic Distortion (THD), lower ElectroMagnetic Interference (EMI) generation and high output voltage. The main feature of Modular Structured Multilevel Inv...

Digital Implementation Of Sinusoidal Pulse Width Modulation Generator

This is the digital implementations of Sinusoidal Pulse Width Modulation (SPWM) generators based on analog circuits. The FPGA based SPWM generator is capable to operate at switching frequencies up to 3 MHz, thus it is capable to support the high switching frequency requirements of modern single-phase dc/ac power converters. The Existing design the switching operation is in 1 MHz. Additionally, ...

Dual Amplitude-Width Pulse Interval Modulation for Optical Wireless Communications

In this paper, a new modified digital pulse interval modulation called Dual Amplitude-Width Pulse Interval Modulation (DAWPIM) is presented, on the basis of Pulse Amplitude Modulation (PAM) and Pulse Width Modulation (PWM), and its properties are presented. After introducing symbol structure, data rate improvement, average normalized power requirement and bandwidth efficiency are studied. The p...
