Abstract:
Sinusoidal pulse width modulation (SPWM) technique has been widely used in inverters and motor driver ciruits. In this paper, SPWM was generated by a low cost HT66F50 single-chip, wherein the reduced sampling points of a sine wave, and the fewer sampling points were then used to produce SPWM singals. The full-bridge inverter was modulated by the high switching frequency SPWM for the high side switches and the 60Hz control signals for the low side switches. Thus, it not only reduces the required memory spacein MCU, but also reduces the switching power losses. When the SPWM frequency is 19.53 kH

<p>This paper presents a comparison between two switching techniques namely Phase Offset Disposition Sinusoidal PWM (POD-SPWM) and Symmetrical PWM switching for a generalized current source multilevel inverter (MCSI) topology. One of the advantages of MCSI is it can reduce the total harmonic distortion (THD) at the output load current with a sinusoidal current waveform. In this paper, the generalized MCSI with the different levels has been developed with Matlab@simulation software in order to study the performance of the two switching schemes for the operation of the MCSI.

Abstract:
Direct drive wind power system need full-scale high power converter, such as flying capacitor multilevel converter. On the realization of high power electronic equipment, an important problem is that the working frequency of high power devices is too low to apply excellent modulated technique such as PWM. In large-power equipment, the switching frequency of power electronics devices is such low that good control performance can't be obtained with a single converter. In order to overcome this problem, Carrier phase-shifted SPWM technique (CPS-SPWM) has been researched. Reactive power compensati

In the full power wind power system, the cage induction wind generator-rectifier system can be regarded as a independent part if the DC voltage could be always controlled constant by inverter part. The prospective AC voltage and frequency of induction generator is dependent on the specific speed and input power, which is obtained by use of SPWM. All rectifier switching state and the alternating moments can be calculated by switching function given by SPWM control.

Abstract:
The classic voltage space vector PWM (SVPWM) is a kind of symmetrical regular-sampled PWM with zero sequence component added to its modulating wave. The technique of carrier phase shifted SPWM (CPS-PWM), which combines the multilevel with SPWM technique, is characteristic of high equivalent switching frequency of the output wave. A technique named sample time staggered SVPWM which combines SVPWM with CPS-PWM is presented in this paper. In order to reduce the maximum switching current, the zero sequence component added into the individual converter units can be adjusted dynamically according to

Abstract:
Power inverters, used to convert DC power to AC, are often used in e.g. solar power applications. However, they tend to be impractically large and expensive; as such, power miniaturization is an active research area. In this thesis, several classes of modern power inverters are evaluated and compared with regards to size, efficiency and output quality in order to identify areas of potential improvement. Methods for estimation of THD, power losses and input ripple are created and verified against a simulation of a five-level neutral-point-clamped inverter with SPWM control. Finally, this design

Abstract:
This chapter focuses on the electric field-induced formation of a single nanoscale polarization domain, emphasizing that nucleation, growth, and annihilation of such a domain enables injection of non-equilibrium domain walls. The focus on nanoscale domains is motivated in large part by advances in scanning probe microscopy (SPM), where the ever-increasing drive to improve spatial resolution was met by a natural reduction of the size of one of the electrodes in a ferroelectric capacitor down to nanoscale dimensions. In this case, the process of ferroelectric switching becomes dominated by the nucleation of a single domain of the opposite polarization. Once allowed to equilibrate, the end-result of the single-domain switching is injection of a new domain wall(s) into the original ferroelectric volume. Likewise, reversing the polarization under the probe will in general eliminate the domain wall(s). The nanoscale ferroelectric switching becomes, therefore, an efficient approach to inject and erase DWs on-demand. However, its primary value may be in facilitation of detailed understanding of the DW injection mechanisms as well as investigation of the range of possible DW configurations, that can be injected up to the highest fields achievable in a given material.
