This work proposes a hybrid space vector modulation (HSVM) scheme for multiport converters (MHCs). Moreover, the impact of shifting auxiliary currents from main ones is proposed and investigated in order to enhance converter efficiency. The operational schemes have been implemented three-phase 5 kW MHC prototype. It shown that HSVM can improve efficiency by 0.3% at full load with respect modula...

Binding and signaling proteins based on Escherichia coli alkaline phosphatase (AP; EC 3.1.3.1) were designed for the detection of antibodies. Hybrid proteins were constructed by using wild-type AP and point mutants of AP [Asp-101 --> Ser (D101S) and Asp-153 --> Gly (D153G)]. The binding function of the hybrid proteins is provided by a peptide epitope inserted between amino acids 407 and 408 in ...

Ohio University is continuing to conduct research to improve its system for weather data dissemination to aircraft. The current experimental system transmits compressed weather radar reflectivity patterns from a ground based station to aircraft. qlthough an effective system, the limited frequency spectrum does not provide a channel for transmission. This introduces the idea of a hybrid modulati...

In this paper, we propose a hybrid M -ary Quadrature Amplitude Modulation (M -QAM) transmission scheme that jointly uses adaptive modulation and selection combining for singular value decomposition (SVD)-based multiple-input multiple-output (MIMO) systems (AMSC-MIMO). We derive exact closed-form expressions of the performance of the proposed scheme in terms of the average spectral efficiency an...

In this paper, the performance and feasibility of a hybrid wavelength division multiplexing/time division multiplexing passive optical network (WDM/TDM PON) system with 128 optical network units (ONUs) is analysed. In this system, triple play services (video, voice and data) are successfully communicated through a distance of up to 28 km. Moreover, we analysed and compared the performance of va...

Binary displays for virtual reality can achieve low latency by integrating view tracking with modulation. We present a novel modulation scheme that combines tracking, pulse density modulation, and pulse width modulation to minimize grayscale artifacts. The hybrid modulator is applied to an AMOLED display at an update rate of 1.7 kHz on which we observe nearly zero latency in the perceived image.

In this paper, we present the performance of a hybrid modulation technique derived from binary frequency shift keying. In the hybrid scheme, each frequency is allowed to be phase modulated with any of p discrete, equally spaced phase shifts. The spectral separation between frequencies, A f , is chosen to make the carriers orthogonal, thus generating a multidimensional modulation scheme. The per...

Two novel structures of permanent magnet (PM) machine, namely a hybrid excitation flux modulation machine (HEFMM) and a variable flux memory machine (VFMM), which have excellent field-weakening capability, are presented in this paper. The HEFMM incorporates the advantages of parallel hybrid excitation structure and flux modulation structure, so as to increase the torque density as well as incre...

This paper presents a modulation extension control algorithm for hybrid cascaded H-bridge multilevel converters. The hybrid cascaded H-bridge multilevel motor drive using only a single dc source for each phase is promising for high-power motor drive applications since it can greatly decrease the number of required dc power supplies, has high-quality output power because of its high number of ou...
