The back-to-back converter is widely used in 4-quadrant adjustable speed drive (ASD) system, active power filter (APF) and wind power grid system attributed to its high power factor and low current harmonics on grid side. In order to attain better performance in driving induction motor of 55kW, the nominal value of DC-link voltage is determined at 700V, which puts forward high request on converter design. As a result, this paper aims to design and analyze DC busbar properly, so that stray parameters can be reduced as much as possible. The impacts of laminated arrangement, dimension of busbar as well as mechanical layout on stray inductance are considered in detail. In this paper, Ansoft Q3D is used to discuss their impacts on stray inductance quantificationally. Equivalent circuit of commutation loop is also analyzed to extract inductance from experimental results accurately. Finally they are verified by the experiment results.

“…Input EMI filter is a general method to eliminate the serious common-mode emission problem in order to satisfy prevailing EMI standards. There is no DC stage common-mode parasitic capacitor in the matrix converter which would augment the coupling between the grid side and the machine side [25]. Hence, we will analyze whether the input inductance of front-end impedance would introduce significant influences on )…”

This paper introduces an equivalent circuit analysis method to investigate common-mode effects in matrix converter applied in wind energy systems. Transfer characteristics of common-mode current against emission sources are analyzed in order to identify the coupling of transfer functions due to absence of DC link. The comprehensive analysis results provide insight into the common-mode current generation, coupling, and transmission. In addition, the matrix converter time-domain model is established with accurate parasitic parameters from experimental measurements. The validity and effectiveness of analysis method has been verified by timedomain simulation.

“…To minimize the undesired power dissipation it can be recommended that in the place of wire and cable sleeves printed circuit boards (PCB) (for low power conversion) or laminated copper busbars (for high power conversion) are highly recommended to be implemented [4], [5]. The nominal current for PCBs trace can be found as…”

Abstract. This paper presents some design guidelines for a new voltage fed step-up DC/DC isolated converter. The most significant advantage of proposed converter is voltage buck-boost operation on single stage. The most promising application for proposed converter is in the field of distributed power generation e.g. fuel cells or photovoltaic.The most sensitive issues -such as power losses caused by high currents in the input side of converter and high transient overvoltages across the inverter bridge caused by stray inductances were discussed and solved. The proposals and recommendations to overcome these issues are given in the paper. The Selection and design guidelines of converter elements are proposed and explained.The prototype of proposed converter was built and experimentally tested. Some results are presented and evaluated.
