When power grid voltage sag occurs simultaneously with some other power quality problems, it will be necessary to install a variety of power quality conditioners. In order to effectively analyze potential interaction resulted from combined operation of the series and shunt compensation devices with no common dc bus. This paper has deeply derived the impedance models of DVR and DSTATCOM, then illustrates...
This paper presents the dynamic analysis of the interaction between an Interleaved Boost Converter with Coupled Inductor (DPCI) and a Constant Power Load (CPL). In order to perform the analysis, the analytical determination of the output impedance of the DPCI is presented, as well as the input impedance of CPL. Then, the same analysis is proposed for a conventional Boost Converter in order to compare...
With the formation of ultra high voltage AC/DC power network, the inherent characteristic of China power grid becomes increasingly complicated. Online stability assessment is one of the effective method to understand the system status in time. To improve power system stability with radical change, it is necessary to automatically identify the weak transmission sections. The paper presents the weak...
This paper discusses the design of a 60 GHz low noise amplifier (LNA) using a standard low power SOI CMOS process from ST Microelectronics. First, we outline the technology as well as the mm-wave design challenges. Using recent work on coplanar waveguide (CPW) modeling, we describe how it's possible to use parametric, 3D electromagnetic simulation to complete or replace analytical models of on-chip...
