This article proposes a scheme for balancing the voltage of series-connected insulated gate bipolar transistors (IGBTs), which is also very effective under short-circuit conditions. An optimized clamp-mode snubber proposed, including an active-driver to balance currents IGBTs during short-circuit, in turn allows considerable reduction capacitance. The approach proven be conditions by maximum 55...

A systematic method for approximating the complex-order Laplacian operator by realizable integer-order transfer functions is presented in this work. The realization performed a simple structure where only one active element used. Thanks to employment of impedances, both integrators and differentiators can be readily implemented same core simply interchanging associated impedance locations. vali...

tac (time to amplitude convertor) is one of the most important time measurement instrumentswhich has great significance in many fields of science, especially radiation physics. a tac unit has beendesigned based on the start-stop analog method and nim (nuclear instrument modules) standards. afterdesigning the circuit, it was simulated by pspice software and constructed by discrete and integrated...

In this work, a full circuit of memristor-based neural network with weighted sum simultaneous perturbation training is proposed. Firstly, synaptic designed by using pair memristors, which can represent negative, zero, and positive weights. Secondly, the designed, all operations being completed on without any computer aid. The trained algorithm. algorithm does not involve complex derivative calc...

The design of a low-pass-frequency filter with the electronic change approximation characteristics resulting responses is presented. also offers reconnection-less reconfiguration order (1st-, 2nd-, 3rd- and 4th-order functions are available). Furthermore, control cut-off frequency output response. feature in investigated for Butterworth, Bessel, Elliptic, Chebyshev Inverse approximations. verif...

In this work, the design of current mode Fractional order filter using VDTAs (Voltage differencing trans-conductance amplifier) as an active element with grounded capacitors has been proposed. The approximate transfer functions low and high pass filters fractional on basis integer shown form those is also implemented VDTA building block. different sequence have realized. frequency domain simula...

In this paper, a new voltage controlled first order all-pass filter is presented. The proposed circuit employs a single differential voltage dual-X second generation current conveyor (DV-DXCCII) and a grounded capacitor only. The proposed all-pass filter provides both inverting and non inverting voltage-mode outputs from the same configuration simultaneously without any matching condition. Non-...

In this paper, an active implementation of a differential voltage current conveyor (DVCC) based on low-pass filter operating in the fractional order domain is presented. The transfer function for system dependent rational approximation sα. Different methods used calculating approximation, including Carlson, Elkhazalil, and curve fitting, are evaluated here. Finally, to validate theoretical results...
