This paper proposes a novel multi-function isolated three-port bidirectional DC–DC converter for stand-alone photovoltaic (PV) system. The proposed topology was composed of unidirectional step-up and step-up/step-down that only required one set complementary PWM signals to control any operation mode used multiple operating stages improve the practicability converter. In addition, had function i...

Abstract-Voltage sag or unbalance conditions at the input rectifier stage of the ac-dc-ac rectifier-inverter induction motor drive can cause the significant amounts of harmonic voltage at twice the line frequency 2f1. This voltage ripple can have a degrading effect on the induction-machine performance characteristics. This paper presents an analytical closed-form mathematical model and analysis...

By using a hybrid scheduling algorithm consisting of static offline scheduling and dynamic online scheduling, hard deadlines can be guaranteed, while achieving optimal resource utilization by soft real-time activities. This paper introduces a medium access control (MAC) protocol for a CSMA bus, which supports the hybrid scheduling of hard and soft real-time messages on the bus. The key issues c...

This paper examines the performance of distributed-shared-memory systems based on the Simultaneous Optical Multiprocessor Exchange Bus (SOME-Bus) using queueing network models and develops theoretical results which predict processor utilization, message latency and other useful measures. It also presents simulation results which compare the performance of the SOME-Bus, the mesh and the torus us...

This paper presents a control scheme which controls in which PV (Photovoltaic) and Fuel cell system are connected through a DC bus. In order to achieve maximum utilization of distribution generation, power supplied to load for day and night through renewable resources. PV power availability is depends upon the solar irradiation so that it becomes important to extract maximum possible power from...
