Performance Comparison of a Typical Nonlinear Load Supplied by ac and dc Voltages

Performance Comparison of a Typical Nonlinear Load Supplied by ac and dc Voltages

This paper presents a performance comparison of a typical nonlinear load when supplied by ac or dc voltages with the same rms value. The performance of the nonlinear load towards its connection to ac and dc power grids is accomplished in terms of the waveforms and efficiency. A simulation model was...
