This article presents a brushless DC motor drive using solar photovoltaic (PV) array and grid. Solar PV array-fed systems typically need DC–DC converter stage in order to optimize the array-generated power utilizing maximum point (MPP) tracking technique. In this work, boost is used for MPP purposes. work utilizes an incremental conductance (INC) MPP-tracking algorithm. A bridgeless asymmetrica...

In this digest, we will present a methodology that allow us to accommodate the conducted Electromagnetic Interference (EMI) generated by power factor correctors to international standards in the design step. EMI filter design considerations and EMI predictive procedures are presented. The predictive procedures are based in a family of curves that allows us to determine the conducted Electromagn...

Using the idea of the optimal decomposition developed in recent papers [EK2] by the same authors and in [CUK] we study the boundedness of the operator Tg(x) = ∫ 1 x g(u) du/u, x ∈ (0, 1), and its logarithmic variant between Lorentz spaces and exponential Orlicz and Lorentz-Orlicz spaces. These operators are naturally linked with Moser’s lemma, O’Neil’s convolution inequality, and estimates for ...

Absstract-The control of switching dc-dc converters is reviewed. Regarding it as a general linear quadratic regulator (LQR) problem, an innovative optimal and robust digital controller is proposed. The control strategy adopted can achieve good regulation, rejection of modest disturbances, and more significantly, the ability to cater to switching converters with RHP zeroes. This controller desig...

Three new bridgeless single-phase ac–dc power factor correction (PFC) rectifiers based on Cuk topology are proposed. The proposed topologies are designed to work in discontinuous conduction mode (DCM) to achieve almost a unity power factor and low total harmonic distortion of the Input current. The DCM operation gives additional advantages such as zero-current turn-ON in the power switches, zer...

This paper presents the design of an auxiliary power distribution network for an electric vehicle. Efficiency is a key element in the design for any electric vehicle and a 48Vdc distribution network will be used throughout the vehicle. The high efficiency Cuk converter has been selected as the most appropriate topology to supply the various distributed loads. To achieve the best compromise betw...
