A new two-input Hybrid Boost-SEPIC (HYBOSPC) DC-DC converter suitable for drawing power from two different DC sources feeding a common DC-bus is presented in this paper. This is a two-switch converter belonging to the seventh-order family and performs boosting operation. The salient feature of the proposed converter is that both the sources are simultaneously supplying power to the downstream load...
The paper brings into depiction a novel two input DC-DC converters topology, for DC micro-grid applications. The paper proposes a topology which is capable of providing excessive bucking with one source and also boosting operation. On account of excessive stepping down of the input dc voltage the converter uses additional energy storage components and hence it belongs to seventh order family. The...
A new two-input DC-DC converter suitable to draw power from two different dc sources feeding a common dc-bus is presented in this paper. This is a two-switch converter belongs to sixth-order family and performs bucking operation for one dc source while it allows both bucking as well as boosting feature with the second source. The salient feature of the proposed converter is that both the sources either...
This paper is about simulation design of an Electronic Control Unit (ECU) for an adaptive cruise control (ACC) and for an engine management system (EMS). The simulation model allows processing of various sensors data like engine speed, engine temperature, and distance from the front vehicle. By collecting data from various sensors, ECU controls the vehicle speed by using electronic fuel injector actuator...
Self Excited Induction Generator (SEIG) is identified as isolated power source, whose terminal voltage and frequency are controlled by varying speed, excitation capacitance or load impedance. Since load changes from time to time, the output parameters mostly are controlled by either speed or by varying excitation capacitance. To reduce the complexity in analysis, the speed of a prime-mover driving...
Several techniques are available for speed control of induction motor drive. The Direct Torque Control (DTC) method is simple and efficient because of independence of rotor parameters and free from d-q transformation. It is observed that dynamics of DTC drive can be improved by using estimators, observers, and machine intelligence systems. This paper proposes a new technique namely Sector Advancing...
Spindle motors are driving to high speed and compact size in Hard Disc Drive (HDD) area, particularly those in servers. In order to read and write the huge data with fast rate, the spin speed of spindle motor should be high with high starting torque. This paper presents a novel topology to a low cost converter which drives a spindle motor at high speed with high starting torque utilizing the bipolar...
