Universal power converters (UPCs) have aroused significant attention in performing multiple operations a single converter. Furthermore, they contribute to economic operation and improved system performance. In this work, new configuration of the universal converter (UPC) was proposed by using simple switching arrangement. It can perform different modes operations, such as AC–DC, DC–DC, DC–AC, A...

In this study investigation is done on an H-bridge switched inductor base cascade multilevel DC-DC boost converter. The proposed multilevel DC-DC boost converter topology improves the conversion efficiency of traditional topology. The proposed boost converter topology is differing from the traditional topology by the addition of switched inductor circuit. The switched inductor improved the conv...

This paper introduces a bi-directional DC-DC converter with adaptive fuzzy logic controller (AFLC). Bi-directional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains, the converter operates as buck converter, powers the down stream converter, and also charges the battery. When the DC mains fails,...

Controlling of DC-DC converter is vital task in power conversion. DC-DC converters are used in many applications like solar charger, computer power supplies, switching mode regulators, aircrafts etc. Focus of this paper is to model a controlling system for buck converter which controls output of buck converter constant instead of changing load and input supply to buck converter. Controlling met...

This research work presents thorough analysis a system under different configurations. Ma...

This paper describes the design of a CMOS capacitor-ratio-independent and gain-insensitive algorithmic analog-to-digital (A/D) converter. Using the fully differential switched-capacitor technique, the A/D converter is insensitive to capacitor-ratio accuracy as well as finite gain and offset voltage of operational amplifiers. The switch-induced error voltage becomes the only major error source, ...

This paper presents a new soft switching flyback-forward PWM converter. The proposed circuit employs an auxiliary circuit to achieve soft switching condition for switches and also absorbs the voltage spikes caused by the leakage inductance of transformers in the converter. In the proposed converter main switch operates at ZVS and the auxiliary switch operates at ZCS. The proposed converter has ...

In this paper, a direct ac-to-dc power converter is proposed for efficient energy harvesting from the low voltage inertial micro generators. The conventional power converters use diode bridge rectifiers and condition the micro generator outputs in two stages. Hence, they are inefficient and may not be a feasible option for very low voltage micro generators. Moreover, they are not conducive for ...
