ZVS/ZCS Bidirectional DC-DC Converter for DC Uninterruptable Power Supply
An Isolated ZVS/ZCS bidirectional DC-DC converter for DC Uninterruptable Power supplies is presented in this paper. The usual way to avoid a computer shutdown during the mains failure is to connect an ac uninterruptible power supply (UPS). Alternatively, in this paper, a simple and high efficiency dc UPS is presented by an isolated bidirectional soft-switching dc-dc converter. The bidirectional...
متن کاملIntegrated Power Devices Simplify an Embedded Dc-dc Power Supply
A new class of integrated power devices has been developed to simplify embedded dc-dc power supply designs. The paper includes comparison with existing discrete/co-package solutions and a new methodology that has been developed in how integrated devices are being designed, specified, tested and qualified. The paper also details how treating integrated devices as power supply modules instead of ...
متن کاملBoost Converter for Power Factor Correction of DC Motor Drive
With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...
متن کاملAC/DC Converter with Active Power Factor Correction Applied to DC Motor Drive
–Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The per...
متن کاملMPPT Based Dc-Dc Converter with ZVS & ZCS Technique
In this paper, a DC–DC converter topology with a zero voltage and zero current switching control technique [8] has been proposed for solar PV applications. The proposed converter combine the feature of buck–boost operation capability, at the same time, it can carry out zero voltage and zero current switching on the primary side of the converter transformer. The proposed work has been carried ou...
