Analysis of seismic waveforms using full-bridge voltage source inverter
نویسنده
چکیده
The current research talks about a designed accelerometer system which is able to measure every type of mechanical vibration. The applied vibration in this survey is called seismic wave. Then the measured wave by this novel system is transf ormed to a specif ic function using spline interpolation. This explicit function can be used as a reference signal in the technique PWM to be made in current form in such a way that it becomes exactly similar to the shape of vibration wave caused by the inverter of twobranch, full-bridge voltage supply. The aim is eventually to use this approach for some technical applications such as designing of an seismic table.

The Dynamic Voltage Restorer (DVR) is a commercially available, popular device to eliminate voltage sags and swells in the distribution lines. Its basic function is to inject the voltage difference (difference between the pre-sag and sag voltage) to the power line and maintains the pre-sag voltage condition in the load side. The efficiency of the DVR depends on the performance of the efficiency...
