Researchers at the University of Yaounde I, Cameroon, have proposed using the Duffing oscillator to amplify low-voltage outputs under low solar radiation conditions, such as at dawn and sunset. According to the researchers, the system amplifies and regulates the low-voltage input using a Duffing oscillator, an inverter, and a summing device. Experimental results show that the system can achieve an output of 7.03 V from an initial input of 0.43 V, reflecting a gain of 24.3 dB. The amplification process is nonlinear, providing significant voltage boosts at weak inputs. The researchers claim that the Duffing oscillator offers more efficient amplification for very low voltages, compared to conventional boost converters.
