Improved Unified Power Quality Conditioner Design and Numerical Simulation for Power Quality Improvement
Abstract: Harmonic currents can distort the waveform voltage, resulting in a weak signal. There is also an increase in the number of loads requiring enough sinus tension to function properly. As electronic devices become more power-sensitive, people are becoming increasingly interested in power conditioning solutions. Therefore, if the amount of electricity being generated falls below a certain threshold, some type of compensation must be provided. Unified Power Quality Controller (UPQC) is …
