Research Abstract |
This research project discusses the application of a single-phase PWM control method to solar power conditioners to satisfy both low-loss and low-noise demands. The theoretical and experimental discussions in this project reveal that the proposed method can suppress the harmonic current even when the switching frequency is decreased to 1/3. The proposed method also makes it possible to reduce the switching power losses to 1/7 and the core losses in the ac inductor to 60%.
