An interleaved current-fed capacitor-less DC/AC converter for PV systems is proposed in this paper with the merits low input current ripple, high power density and high reliability. This proposed DC/AC converter is composed of an interleaved current-fed dc/pulsating-dc converter cascaded with a three-phase pulsating-dc/ac inverter through pulsating-dc-link modulation. The pulse width modulation of...
An optimized modulation based on model predictive control for current-fed dual active bridge converter achieving high efficiency in wide load range is proposed in this paper. The low voltage side switches can realize zero current switching by secondary clamping technique. The pulse width modulation of secondary side switches is encoded with instantaneous power. When in light load, the turn-on moment...
Realistic wrinkles are important for enhancing the realism of 3D facial expression. In this paper, we proposed a combined method to simulate realistic wrinkles generated in facial expressions. By taking physiological mechanism of facial wrinkles into account, we used the muscle model for facial animation to extract the wrinkle region, and then an improved wrinkle model was applied to generate wrinkles...
The rendering of lines for 3D models is an important research topic in NPR(Non-Photorealistic Rendering). In line drawing, the use of loose style can help artists express their emotion and depict objects vividly. In this paper, we summarized the aesthetic factors of loose line style in two aspects: line thickness and line omission, and proposed a mathematical description for it. We also provided a...
An input-parallel output-series full-bridge DC/AC converter for on-board Electric Vehicle (EV) charger is proposed in this paper with the merits that low input current ripple and output voltage ripple. It can also decrease the current stress on the primary side devices and voltage stress on secondary side devices. This proposed DC/AC converter interleaves two isolated full-bridge converters with parallel...
This paper proposes a novel scheme for the next generation of terrestrial broadcasting (NGTB) on high speed railway (HSR). A hybrid broadcasting and wireless communication network for HSR can improve the average throughput for passengers on high speed trains (HST); whats more, the broadcasting network is more efficient than communication network if the common hot information is delivered. A novel...
Wireless chip area networks (WCAN) signify a new development in wireless communications, where wireless interconnections among different cores within a chip (intrachip) or among different chips within a module (inter-chip) can be realized. In this paper, we analyze bit-error rate (BER) of an ultra-wideband (UWB) radio with binary phase-shift keying (BPSK) modulation over an inter-chip wireless radio...
