A systematic derivation of DC-circuit and small-signal-circuit models and characteristics for pulse-width-modulated buck-derived convertors operating in the continuous conduction mode is presented. Starting from voltageand currenttransfer functions of an idealised switching part of the convertor and using the linearisation technique, pure linear-circuit models of lossless convertors are derived...

This paper presents an interface circuit with power control features for electrostatic vibration energy harvesting. A DC-DC convertor is used to control the output voltage of a diode-based charge pump circuit. Therefore, the maximum and minimum voltage across the variable capacitor of the energy harvester may be adjusted to track the maximum power point of the system. The power conversion funct...

A single multi-plane light convertor (MPLC) is applied to simultaneously mitigate turbulence-induced crosstalk and demultiplex two orbital angular momentum (OAM) multiplexed channels for a free-space optical link. Comprised of six programmable phase planes, the MPLC placed at receiver side turbulence mitigation channel demultiplexing. Propagating through cascaded coaxial turbulence-distorted OA...

in this paper, a new method is introduced for improving the efficiency of the residue number system, which uses both binary and residue representations in order to represent a number. a residue number system uses the remainder of the division in several different modules. conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

Voltage to current converters or TRANSCONDUCTANCE amplifiers, find its applications in both traditional analog ICs e.g. amplifier and filters as well as current analog VLSI e.g. Field programmable analog arrays and various other neural networks. A complete review of different linear V-I converter has been done in this paper. Since the basic V-I convertor circuit uses common source differential ...

This paper summarizes the development of the synchronization control technology of the multi-motor control system. And a model structure of multi-motor synchronization control system based on the monomaster PROFIBUS-DP network is proposed, which slaves are intelligent including PLC, convertor and motor. The communication mode of MS is adopted. The control tasks of the master and their slaves ar...

This paper presents an influence issue improved by victimisation buck-boost convertor for BLDC motor drive as a value effective answer for low power applications. AN approach of speed management of BLDC motor by dominant the DC link voltage of VSI (Voltage supply Inverter) is employed. This facilitates the operation of VSI at fundamental change by victimisation the electronic commutation of BLD...
