Abstract— In this research, a single phase Z-source cascading Multilevel Inverter, Nine-level inverter topologies with a trinary DC sources are offered. The recommended topologies are expanded by cascading a full bridge inverter with dissimilar DC sources. This paper recommends advanced pulse with modulation technique as a switching scheme. In this PWM technology, trapezoidal modulation techniq...

This paper proposes an M-ary amplitude shift keying (MASK) power and information synchronous transmission system based on phase-shifted full-bridge (PSFB) for applications in wireless (WPT). The Pulse Width Modulation (PWM) waveform uses different phases to control the MOSFET inverter MASK modulation. voltage generates M transformation, forming a comprehensive flow. demodulation circuit process...

Inverters inherently have the property of controlling output frequency but the output voltage can’t be varied. Usually to vary output voltage we have to vary supply voltage which is not always possible for this reason PWM techniques gained momentum. Basic aim of PWM technique is to control output voltage and harmonic reduction. Pulse-width modulation (PWM), or pulseduration modulation (PDM), is...

With the advances in semi-conductor devices, adjustable speed drives (ASDs) have become more prevalent than ever before in industrial and commercial processes. Many facilities are installing ASDs to improve the efficiency of their processes and to increase the control of their processes. While the effects of ASDs on the power system are well known, many engineers and systems integrators are not...

This paper presents the sound art installation Doppelgänger. In Doppelgänger, we combine an artistic concept on a large scale with a high degree of control over timbre and dynamics. This puts great demands on the technical aspects of the work. The installation consists of seven 3.5 meters-tall objects weighing a total of 1500 kilos. Doppelgänger transfers one soundscape into another using audio...

We show both analytically and numerically that photons from a probe pulse are not stored in several recent experiments. Rather, they are absorbed to produce a two-photon excitation. More importantly, when an identical coupling pulse is re-injected into the medium, we show that the regenerated optical field has a pulse width that is very different from the original probe field. It is therefore, ...

The multilevel inverters have become more popular during the recent years. The multilevel inverters are applied in many industrial applications such as static VAR compensators, AC power supplies, drive systems, active power filters, etc. The topologies of multilevel inverter have several advantages such as low distortion in output voltage with relative low switching frequency, low harmonic and ...

This letter describes an alternative solution to passive and active filter arrangements on the dc side of the converter. The circuits of dc-side ripple elimination are based on direct reinjection of the ripple in series with the dc line.
