In this paper, a soft-switching single-ended-primary-inductance converter (SEPIC) with multi-output sources is proposed. The proposed SEPIC has the following advantages: (1) The conversion efficiency can be increased. To incorporate a soft-switching cell with a flyback-type, the power switches can achieve zero-voltage-switching (ZVS) and zero-current-switching (ZCS) features under turn-on trans...

The continuous growth of SWITCHMODETM Power Supplies (SMPS) worldwide makes this market one of the most important for manufacturers of power semiconductors. It is particularly important for manufacturers of devices in the 3 A to 10 A current range since most of these power supplies are designed to deliver power in the range of 50 to 1000 W. Although MOSFETs are often preferred for the new desig...

Abstract In engineering practice, a constant voltage output control system of synchronous rectifier primary side regulator (PSR) flyback converter is proposed to overcome the sampling defect existing digital approximation double line scheme for structure. Regardless slope waveform and knee point, single-output DAC midpoint can achieve high accuracy good point following effect. At same time, neu...

The paper presents unified modeling and analysis of high-power-factor rectifiers based on switching converters with nonlinear-carrier control (NLC). In NLC control, which offers simple, high-performance power-factor correction (PFC), the switch duty ratio is obtained by comparing a signal derived from the switch current with a periodic nonlinear carrier. A general expression is derived for the ...

This paper presents an analysis and system-level design of a capacitive harvester of vibration energy composed from a mechanical resonator, capacitive transducer and a conditioning circuit based on the BUCK DC-DC converter architecture. The goal of the study is to identify optimal power performance of the system, to understand the electromechanical coupling phenomena and to propose the optimal ...

This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. However Conventional standby mode control techniques have some problems such as audible noise and poor regulation. In proposed techniques, basical...

KHAN, MOHAMMAD SAMEER. Analysis of Flyback-PV Inverter to Enable Low Voltage Ride-Through (LVRT) Operation During Grid Fault. (Under the direction of Dr. Subhashish Bhattacharya). Flyback based PV micro-inverter is a very popular low-cost solution for integrating the photovoltaic (PV) module to an AC grid. As the penetration level of these inverters in the grid is increasing, it may cause probl...

This paper focus on a special type of inverter topology for photo voltaic applications. The proposed system is a grid connected inverter system based on interleaved flyback topology. Aim of this paper is to design flyback inverter at high power because today’s PV inverter technology based on this topology only used at very low power as micro inverter. The analysis of proposed flyback inverter a...
