This paper explores a configuration for boost half bridge DC-DC converters, connected in parallel at the input and series at the output, such that the converters share the input current and load voltage equally. A stable control scheme has been developed to achieve this objective. In order to verify the effectiveness and stability of control scheme, input-parallel output-series (IPOS) connected...

the aim of this paper is to design a fractional order sliding mode controllers (fosmc)for a class of dc-dc converters such as boost and buck converters. firstly, the control lawis designed with respect to the properties of fractional calculus, the design yields an equiv-alent control term with an addition of discontinuous (attractive) control law. secondly, themathematical proof of the stabilit...

A new synchronous rectifier (SR) driving method is proposed using primary current sensing in this paper. Because the magnetizing current of transformer is included in primary winding of transformer, it can’t be used to generate the driving signals of SRs directly. A current compensating winding in current transformer is used to cancel out the magnetizing current and generate suitable driving si...

This paper presents an approach for teaching and learning dc-dc converter design using MathCAD. MathCAD provides advantages that greatly improve teaching and learning process especially when long and complicated design equations are involved such as those found in dc-dc converters. A design example using Excel is presented and then compared with the same example using MathCAD. Experience learne...

In this paper, a new in-package high efficiency voltage down converter (VDC) is presented. Usually, quality factor of inductors is the main problem for generating high efficiency DC-DC Converters. In order to mitigate this problem, Bonding Wires with a new form are exploited in which four mutual inductions of bonding wire are used to increase the total inductance. This technique provides a high...
