| The global positioning system (GPS) is a one-way, all-weather, real-time, and worldwide radio-navigation system. It is also a quite usable tool for accurate time dissemination and for terrestrial atmosphere remote sensing. The system was funded and designed by the US military. The rst GPS satellite was launched in 1978. There are 24 of them currently in orbit around the earth and the whole sy...

Background and Objectives: Power electronics infrastructures play an important role in charging different types of electric vehicles (EVs) especially Plug-in Hybrid EVs (PHEVs). Designing appropriate power converters is the topic of various studies. Method: In this paper, a novel bidirectional buck-boost multifunctional integrated converter is presented which is capable of handling battery and ...

In this paper we describe a generic receiver as a single channel S-band receiver and it is composed of two modules. The first module (down converter) consists of an input band pass filter, LNA, image rejection filter and down-converter with a PLL local oscillator. The second module consists of the IF module derived from the VHF receiver. The IF module consists of a low pass filter, 20MHz band p...

This paper describes the development of a hybrid sensing module consisting of a general purpose electro-optical converter and three MEMS force sensors, to be integrated into flexible substrates for tactile skin applications. The features of the converter, namely its flexible and thin substrate and small dimensions, programmability, optical coding and transmission of the information allow this v...

This paper proposes a novel nine switch converter based integrated power conditioner in place of conventional twelve switch converter based power conditioner for improving power quality. Space vector modulation scheme is proposed for producing gating signals for nine switch converter. In the proposed integrated power conditioner the nine-switch converter replaces shunt and series converters fou...

Nowadays, along with the development of technology of the high-speed Analog to Digital Converter (ADC) and Field Programmable Gate Array (FPGA), the design and the implementation of high-speed and highaccuracy data acquisition system is also becoming economic and feasible. In this paper, we designed a high-speed, high-precision, portable data acquisition and processing system in Altera Corporat...

The loading of free wheel diodes (FWD) and IGBTs in the power modules of a Voltage Source Converter (VSC) are investigated. In converter duty, the FWD is utilized more then the IGBT. Presently, most FWD’s in power modules are optimized for inverter duty. This practice tends to undersize the FWD from a converter viewpoint. This design philosophy is examined in the paper. For this purpose, the or...

A DC-DC converter is designed according to the request of the electric propulsion system for a fuel cell sightseeing car. The converter adopts a simple topography full bridge circuit. The main switch transistors are driven by the module TL494, based on pulse-width modulation method. A high accuracy linear optical coupler is used to isolate analogy signal in order to guarantee the stabilization ...
