Enhanced time-based Interest protocol in content-centric networking

IN recent years, the metal halide lamp has become widely used for indoor lighting, especially in commercial areas, because of its longer lifetime, Enhanced time-based Interest protocol in content-centric networking good color rendering, and high luminous efficiency However, the metal halide lamp suffers from acoustic resonance, which causes light flickering or even arc extinction In order to avoid this acoustic-resonance Enhanced time-based Interest protocol in content-centric networking problem and to meet the electromagnetic interference limitation given by the IEC regulation, as shown in the electronic ballast is operated at radio frequency Since most of the available commercial-controlled electronic ballasts have difficulty in reaching operating frequency, self-oscillating electronic ballast is employed to drive the RF The self-oscillating half-bridge electronic ballast has been widely used in electronic ballast applications.

However, in comparison with the self-oscillating Enhanced time-based Interest protocol in content-centric networking half-bridge electronic ballast, the self-oscillating full-bridge electronic ballast, as shown , is much more suitable for the high-power applications For the development of the self-oscillating electronic ballast, the analysis and design methods have been investigated the time-domain analysis and Hamel locus were used to analyze the self-oscillating parallel resonant inverter from the standpoint of a relay system. Enhanced time-based Interest protocol in content-centric networking According to the literature the accuracy of the operating-frequency prediction via the Hamel locus approach is higher than the accuracy that can be obtained via the describing-function approach.

However, the time-domain analysis is based on the assumption that ideal components are used. Enhanced time-based Interest protocol in content-centric networking When the self-oscillating electronic ballast is operated in RF, the effect caused by gate-to-source capacitor Cgs of the MOSFETs on the self-oscillating gate-drive network becomes a significant influence on the design of the operating frequency. To avoid this effect, a driver that insulates capacitor Cgs from the self-oscillating gate-drive network has been proposed However, with the additional driver, the component count and the cost of the electronic ballast are undesirably increased. Enhanced time-based Interest protocol in content-centric networking In order to avoid the acoustic-resonance problem in the metal halide lamp and to meet the EMI limitation given by IEC regulations, the electronic ballast is operated at and a self-oscillating full-bridge electronic ballast is employed to drive the RF lamp.

Enhanced time-based Interest protocol in content-centric networking Since the self-oscillating electronic ballast is operated at the effect caused by gate-to-source capacitor Cgs of the MOSFETs on the selfoscillating gate-drive network must be considered. Therefore, this paper presents the analysis of the self-oscillating gatedrive network with consideration given to the gate-to-source capacitor Cgs . ANALYSIS OF GATE CONTROL Without Consideration of Gate-to-Source Capacitor In order to simplify the analysis of the self-oscillating gatedrive networks, the following assumptions are made: steady-state operation; use of ideal active and passive components; constant dc-bus voltage; and sinusoidal resonant inductor current waveform. secondary winding LCT,s in the self-oscillating gate-drive network functions as a current source, which can be simply modeled with sinusoidal current source is in parallel with magnetizing inductor to construct an equivalent circuit, as shown in the key waveforms for the equivalent circuit of the self-oscillating gate-drive network. At initial time t0 , feedback current is is equal to magnetizing inductor current im, and Zener current iz reaches zero.
