This Paper presents the design and implementation of a single phase inverter using IGBT as switch and the study of the output responses. The inverter consists of two parts: the control circuit and the power circuit. The control circuit is responsible for generating the gate pulses to trigger the IGBTs. The pulse width modulation technique has been used to obtain pulse width modulated (PWM) puls...

Flip Flops are critical timing elements in digital systems which has large impact on circuit speed and power consumption. The performance of flip flop is an important parameter to determine performance of whole synchronous circuit. In this paper, comparison of existing flip flops with different parameters is calculated. A new design a low power pulse triggered flip-flop (FF) has been proposed h...

This paper describes the design and development of a pulse selector circuit, two different low cost techniques for generation of low jitter variable delays and a high band width line driver for use in the regenerative amplifier stage of a table top Terawatt femto second laser chain. The pulse selector stage selects one pulse from a high frequency laser oscillator, injects it into the regenerati...

This study explains the breakdown mechanism in different triggered spark gap switches. Two different trigger electrode configurations are tested for the switch predischarge operation in a nitrogen laser circuit. The behavior of the breakdown voltage, when a trigger pulse is applied to the trigger electrode, is investigated, and the results are reported. Based on the experimental measurements ne...

surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. a good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. on the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and incr...

A pulsed time-of-flight (TOF) measurement-based Light Detection and Ranging (LiDAR) system is more effective for medium-long range distances. As a key ranging unit, a time-pickoff circuit based on automatic gain control (AGC) and constant fraction discriminator (CFD) is designed to reduce the walk error and the timing jitter for obtaining the accurate time interval. Compared with Cramer-Rao low...
