In this paper, we present a new scenario of direction arrival (DOA) estimation using massive multiple-input multiple-output (MIMO) receive array with low-resolution analog-to-digital convertors (ADCs), which can strike good balance between performance and circuit cost. Based on the linear additive quantization noise model (AQNM), effect ADCs methods, such as Root-MUSIC method, is analyzed. Also...

This paper proposes a minimal switching multiple input multilevel output (MS-MIMLO) DC-DC converter. Minimizing the cost of operation is an utmost priority any electric circuit design. Thus, reduction number switches that control and manage feeding power into MIMLO convertors presented. The proposed MS-MIMLO converter exerts many advantages, include high voltage transfer ratio with small size i...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

Design of traction system is important to decide the dynamic configuration of high speed EMU. And one of the most important factors that determine the design of traction system is the thermal distribution of IGBT convertors. Thermal simulation of IGBT converter using a two-step methodology (temperature rise and thermal distribution) and its simulation results are presented in this paper [1]. Th...

This paper describes a new design strategy which is used to obtain fivefold increase in the 3 dB axial ratio bandwidth of linear circular polarization convertors based on anisotropic frequency selective surfaces composed single screens cross slots. The performance improvement obtained by employing stratified dielectric media carefully tailor shape TE and TM spectral transmission responses. We d...
