A Constant-Power Battery Charger With Inherent Soft Switching and Power Factor Correction
A battery charging circuit, which operates as a constant power source, is proposed in this paper. By maintaining a constant output power throughout the charging process, the circuit reduces the size of thermal installation which would normally be required in the cases of constant-voltage or constant-current charging. The proposed circuit takes the form of a half-bridge converter with an additio...
متن کاملAn integrated battery charger/discharger with power-factor correction
Distributed power-supply systems are an attractive solution to meeting the requirements (redundancy, modularity, battery backup, etc.) for the next generation of power-supply systems. In addition, the normalization regarding power factor and total harmonic distortion (THD) makes it necessary to include the power-factor correction in the input stage in those architectures. This paper presents a ...
متن کاملAnalysis and design of soft-switching power factor correction converter
* This project is funded under the NASA-KSC STTR-Phase I Program. ABSTRACT A single-stage power factor correction converter with softswitching is proposed in this paper. The topology of this converter is derived by adding a resonant circuit to an existing Single-Stage, Single-Switch Power Factor Correction (S PFC) converter. As a result, zero-voltage-switching and zero-current-switching are ach...
متن کاملSoft-Switching Single-Stage Power Factor Correction Converter
1 This work is supported by NASA-STTR grant # NAS10-00005 AbstractA single-stage, ZVT-PWM, power factor correction converter is proposed in this paper. Zero-voltage switching for the main switch and zero-current switching for the auxiliary switch are realized by utilizing the leakage inductance of the output transformer and the capacitance of the switches. As a result, no additional resonant co...
متن کاملWireless Power for Mobile Battery Charger
This Wireless Mobile Battery Charger project is using technique of inductive coupling. The basic concept of his technique was applied in transformer construction. With this technique, the power from AC or DC can be transfer through the medium of magnetic field or air space. In this project, the method is divided into two major activities which is to purpose circuit construction and to fabricate...
