A new single switch solar powered high gain step-up DC-DC converter is proposed for plug-in hybrid battery charger in Electric vehicle (EV). The topology utilizes a L2C3D2network to obtain voltage and reduce the stress on power switch. Additionally, has universal input order suit soft output characteristics of fuel cell. cell relatively low current, it as its drops current increases. Therefore,...

Modern compilers present a great and ever increasing number of options which can modify the features and behavior of a compiled program. Many of these options are often wasted due to the required comprehensive knowledge about both the underlying architecture and the internal processes of the compiler. In this context, it is usual not having a single design goal but a more complex set of objecti...

grain hardness is one of the most important quality characteristics of cultivated bread wheat (triticum aestivum l.) that has main effect on milling yield, particle size, and water absorption of wheat flour. kernel hardness is mainly controlled by ha locus on the short arm of chromosome 5d in bread wheat. in this study, we have employed a multifaceted approach to investigate aspects of grain ha...

This study presents a new high step-up converter based on the voltage multiplier cell and coupled inductor for renewable energy applications such as fuel photovoltaic power systems. achieves conversion ratio using (VMC). The acts passive clamp circuit reduces maximum across switch. suggested topology has only one switch in its structure, which leads to low cost volume. other benefits of propose...

This paper describes a high-frequency soft-switching dc-dc converter with simple energy recovery capacitor snubber on the secondary side. The presented full-bridge removes main drawbacks of classic Phase Shifted PWM (PS-PWM) converter, e.g., circulating current flowing during free-wheeling interval and dependency soft switching load current. utilizes topology pulse-width modulation centre-tappe...

Based on the commutation property of T-type neutral point clamped (T-NPC) three-level inverter, a novel zero-current-transition (ZCT) soft-switching topology is proposed. The proposed employs only two auxiliary switches and one inductor capacitor (LC) resonant tank each phase leg. process technique analyzed. results show that all main leg can achieve soft without changing pulse width modulation...

This study presents a two-switch continuous conduction mode pulse width modulation flyback converter that employs an LC snubber circuit. The snubber circuit is used to achieve zero voltage switching (ZVS) operation for the main switches during the turn-off transition and soft switching for power diodes. With the proposed LC snubber, the magnetic energy in the transformer leakage inductance can ...

We report an optical switch based on a diffraction grating by combining PDMS microstructures with a photo-responsive Nematic Liquid Crystal (NLC). The grating was realized via replica molding and was subsequently coated with a thin SiO layer. SiO induced a full planar alignment of the liquid crystal. The induced parallel alignment of the LC reduces the response time of the structure by approxim...

This paper presents the Zero-Voltage Switching (ZVS) performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. Switching transitions of the transistor occurring in favorable conditions such as device zero-voltage or zero-current is called as soft-switching. The benefits of soft-switching are reduced switching losses, switch stress, low electromagneti...

We study the problem of deadline aware scheduling for input queued (IQ) switches. While most research on scheduler design for IQ switches has focused on maximizing throughput and optimizing switch performance for non-realtime traffic, packet deadlines are a key consideration in the context of real-time applications like multimedia streaming and video telephony. In this paper, we introduce the n...
