The clustering algorithm employing “stochastic association”, which we have already proposed, offers a simple and efficient soft-max adaptation rule. The adaptation process is the same as the on-line K-means clustering method except for adding random fluctuation in the distortion error evaluation process. This paper describes VLSI implementation of this new clustering algorithm based on a pulse ...

Many Wire-EDM machines have adopted the pulse generating circuit using low power for ignition and high power for machining. However it is not suitable for finishing process since the energy generated by the high voltage sub-circuit is too high to obtain a desired fine surface, no matter how short the pulse on time is assigned. For the machine used in this research, the best surface roughness Ra...

In this paper, a voltage-boost-type non-voltage drop single-phase full-bridge inverter connected to switched-capacitor structure is proposed. The output voltage of the controlled by pulse width modulation DSP control lead and break active switches. switches work at low frequency; other high frequency. uses two capacitor modules charge discharge alternately so as overcome problem on side in tran...

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...
