Point distributions with different characteristics have a crucial influence on graphics applications. Various analysis tools have been developed in recent years, mainly for blue noise sampling in Euclidean domains. In this paper, we present a new method to analyze the properties of general sampling patterns that are distributed on mesh surfaces. The core idea is to generalize to surfaces the pair...
In this paper, a novel flying-capacitor-half-bridge 5-level inverter is studied which is composed of a half-bridge capacitor-clamp inverter and a conventional half-bridge inverter connected to a common split-capacitor power supply. Analysis of a modulation technique for the inverter, which incorporates square-wave synthesis in conjunction with the PWM subharmonic method, is illustrated. According...
A novel hybrid flying-capacitor-half-bridge cascade inverter is developed in this paper. The novel inverter is based on connection of multiple single-phase flying-capacitor-half-bridge (FCH) 5-level inverter modules per phase. With the dc bus voltage ratio V1:V2=1 :2, the phase voltage of the novel inverter with two modules per phase will output 13 voltage levels. A new hybrid FCH modulation control...
This paper presents a novel hybrid capacitor-clamp cascade 13-level inverter. The inverter is based on the series connection between two inverter modules with different dc bus voltage. It is the fact of a hybrid control scheme that higher voltage devices and faster devices operate in synergism. Subharmonic PWM method is employed in lower voltage module. In the case of three carrier dispositions, mathematic...
This paper proposed a novel hybrid flying-capacitor-half-bridge 9-level inverter in which flying-capacitor-half-bridge 5-level inverter and an H-bridge inverter with equal dc bus voltage are series connected to form an inverter phase leg. A new hybrid FCH control technique for the novel inverter is proposed. Spectral analysis of output waveform is carried out. The proposed converter is also verified...
