This paper describes design considerations and performance analysis of a novel on-line singlephase to three-phase uninterruptible power supply (UPS) with reduced number of switches. The proposed topology uses only 5 active switches reducing the cost of the system compared to the traditional 10-switch topologies. The proposed UPS consists of a single-phase rectifier/charger, a hvo-leg/three-phase inverter connected to load, battery hank, DC link capacitor and an AC inductor. Detailed circuit operation and analysis as well as simulation results are also presented to verify its feasibility.

Investigation of secondary cooling design enhancements in thermally limited compact notebooks
Khan, Muhammad Azhar Ali; Uzgoren, Eray; Muhtaroglu, Ali (2017-01-01)
Thermal design enhancements in a thermally limited compact notebook system are investigated in this paper. System temperature, power, and fan speed are characterized under a range of activity levels. A finite element model is developed, and validated against measurements. Design enhancements improve cooling with minimum intrusion to the existing mechanical design. A passive secondary heat pipe in the system reduces the CPU temperature by 5 degrees C, and improves the system performance through increased CPU...
Concurrent operation of wireless power transfer based contactless slip ring and motor drive system with a single converter
Ayaz, Enes; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-9)
This thesis presents a novel approach for concurrent power transfer to wired and wireless systems using a single inverter. This proposed approach fits a cost-effective solution to wireless power transfer (WPT) systems used in contactless slip rings (CSR) applications such as sensors, radars, or wind-turbine pitch controls. In conventional systems, there are two separate converters: one is for the motor drive, and the other is for the WPT system. It is proposed that the switching harmonics of the motor drive...
A Detailed Power Loss Analysis of Modular Multilevel Converter
Erturk, Feyzullah; Hava, Ahmet Masum (2015-03-19)
This paper thoroughly examines the semiconductor power loss characteristics of modular multilevel converters (MMC). Power loss behavior is examined under different pulse width modulation (PWM) methods and operating conditions. The effects of stored energy level, circulating current control utilization, power factor and submodule voltage balancing method on power loss are studied. Furthermore, unbalanced power losses and specific semiconductor stresses within a submodule are visualized by investigating the l...
A software for simulation and controller development for high frequency high voltage power supplies
Ertan, Hulusi Bülent; Demirel, O (2000-08-18)
This paper describes a software developed for the simulation of high voltage (up to 125 kV), high frequency power supply for radiology equipment. The main components of the power supply are an AC-DC conversion stage, a high frequency inverter feeding a resonant load. The resonant load is the impedance reflected to the inverter side of the, high voltage high frequency transformer Seeding the X-ray tube. The software has modules for each of the components of the converter mentioned above, which can be modifie...
Design and Performance Analysis of a Grid Connected PWM-VSI System
Kantar, Emre; Usluer, S. Nadir; Hava, Ahmet Masum (2013-11-30)
Pulse-width modulation (PWM) voltage source inverters (VSIs) are favorable interface devices to the power grid for renewable energy systems. This paper deals with the design of the LCL-filter and inverter for the grid-connected VSI. A complete design procedure for both reactive and passive components of LCL-filter is demonstrated with a new iterative approach in selection of the filter inductors. The design process for a two-level VSI is clearly illustrated through an example and the dynamic response is inv...
