Until now, a few explores have been advanced on the PI system which diminishes the size and expense of general structure. In any case, each one of them have been associated with the flyback converter, and it is hard to apply them to the half-connect (HB) LLC converter because of the extensive voltage over the auxiliary spillage inductor of the transformer. In this letter, another PI system for ...

One of the high frequency switching power supply circuits is flyback converter. Due to its inexpensive cost and electrical isolation properties, it mostly employed in low applications. It well known that results losses lowers inverter efficiency, particularly at powers. Consequently, a DC-DC converter run closed control loop explained this study. Closed-loop proposed topology for For same input...

Received Dec 5, 2014 Revised Jan 27, 2015 Accepted Feb 13, 2015 This paper presents a comparative analysis of Integrated boost flyback converter for Renewable energy System. IBFC is the combination of boost converter and fly back converter. The proposed converter is simulated in open and closed loop using PID and FUZZY controller. The Fuzzy Logic Controller (FLC) is used reduce the rise time, s...

This paper presents a comparison of Isolated (Flyback) and non-Isolated (Buck) multiple input-single output (MISO) DC-DC converters. The analysis converters is based on pulsed voltage source cells (PVSC). modeling both converter types detailed through their mathematical models electrical simulations using Matlab/Simulink PSIM. focuses the sizing parameters, non-ideal characteristics efficiency....

This application note describes the single-stage power factor correction (PFC) and presents the design guidelines of a 75W universal-input, single-stage PFC for LED lighting applications. Flyback converter topology controlled by the critical conduction mode control IC, FAN7530 is applied and several functions; such as CV/CC mode feedback circuits, cycle-by-cycle current limit, soft-starting fun...

High power and high voltage gain DC-DC converters are key to high-voltage DC (HVDC) power transmission for offshore wind power. This paper presents an isolated ultra-high step-up DC-DC converter in matrix transformer configuration. A flyback-forward converter is adopted as the power cell and the secondary side matrix connection is introduced to increase the power level and to improve fault tole...
