This paper describes the design and implementations of a single phase high voltage DC power supply at 15 kV output. This explain the detail description of the simulation, design, development and implementation of the hardware work to build a high voltage DC power supply in the laboratory and its simulation works done by using PSpice software. The designed DC power supply it can be used in indus...

The VHDL based mixed-signal event-driven (MixED) simulation method [1] has been shown to allow for effective mixed-signal simulation in a number of useful applications. The range of possible applications is smaller than that of tools such as VHDL-AMS [2,3] or PSpice-AD [4]. However, a number of useful mixed-signal circuits have already been successfully simulated, e.g. an analog inverter with o...

This paper introduce a new current mode Schmitt trigger circuit using a single Current Controlled Differential Difference Current Conveyor Transconductance Amplifier (CCDDCCTA). The circuit is designed using a single CCDDCCTA without any passive component. The proposed Schmitt trigger circuit is designed at a supply voltage of ±1.25V, bias voltage of -0.8V using PSPICE and the model parameter o...

In this paper, a new bipolar technology-based configuration for providing inverting first-order currentmode (CM) all-pass filter response is proposed. One of the main advantages of the introduced active C topology is to have the property of electronic tunability of its pole frequency without requiring passive component matching condition. To show the performance of suggested filter, simulations...

A two level client-server development was performed by web layer (to send remote measurement stimuli + simulation parameters) and workbench layer – implemented under National Instruments “LabView” control. The test bench equipment allows both programming of signals generation / acquisition and PSpice simulation triggering. MS “FrontPage”and Macromedia “Flash”based string concatenation and Intra...

This paper presents an electronically controllable grounded capacitor quadrature oscillator using single multiple-output current controlled current differencing transconductance amplifier (MO-CCCDTA) as an active element. The proposed circuit employs a single MOCCCDTA, two grounded capacitors and one grounded resistor and offers the advantages of (i) independent control of condition of oscillat...

In this paper, we use a single current differencing buffer amplifier (CDBA) in the current mode with application of voltage mode universal filter and all pass filter is presented. The proposed circuit is suitable for realize the proposed operation by using of two CDBA with the current processing application of filter design also we have driven the performance of CDBA. All-pass filter & Universa...

Two PEFC stacks were first tested individually at a level up to 1 kW stack power with and without the embedded control devices, and then ac impedance measurements were conducted after the system reached a steady state. The two stacks containing 47 MEA cells each were connected in parallel using room air and pure hydrogen fuel supply (purity > 99.99%). Next, ac impedance evaluations were conduct...

This study analyzes the absolute stability in P and PD type fuzzy logic control systems with both certain and uncertain linear plants. Stability analysis includes the reference input, actuator gain and interval plant parameters. For certain linear plants, the stability (i.e. the stable equilibriums of error) in P and PD types is analyzed with the Popov or linearization methods under various ref...
