Waveform Generator for Load Susceptibility Testing
نویسنده
چکیده
Power quality test facilities developed at the University of Wollongong include a 10kVA waveform generator (WG) of which the detailed design and operation has been described previously. The WG is essentially a programmable IGBT voltage source inverter controlled by a micro-controller. The original intention of this generator was to test electrical equipment under the influence of harmonic distortion. This paper describes the work undertaken in further development of the WG operation to produce controlled voltage unbalance, sags and swells, and fluctuations.

A sine waveform signal generator for the on chip testing of mixed-signal circuits for speech processing is present. The idea behind is to attenuate the higher frequencies in a periodic triangular waveform. The hardware implementation is discussed. And the simulation results validate our proposal. This generator can be employed for both the digital BIST and the analog/mixed-signal BIST applicati...

متن کاملLow-Distortion Sinewave Generation Method Using Arbitrary Waveform Generator
This paper describes algorithms for generating a low-distortion single-tone signal, for testing ADCs, using an arbitrary waveform generator (AWG). The AWG consists of DSP (or waveform memory) and DAC, and the nonlinearity of the DAC generates distortion components. We propose here to use DSP algorithms to precompensate for the distortion. The DSP part of the AWG can interleave multiple signals ...
