Duffing oscillator can increase low output voltages in PV systems at dawn, sunset

Scientists have utilized a device based on the Duffing oscillator to solve the problem of PV systems' low efficiency at low input voltages at dawn and sunset. Its performance was reportedly better than that of a conventional DC-DC boost converter in amplifying weak input voltages. Researchers at the University of Yaounde I in Cameroon have proposed to use the Duffing oscillator to amplify very low-voltage output with low solar radiation levels at dawn and sunset. The Duffing oscillator, or Duffing equation, is a differential equation used to model certain damped and driven oscillators. Named ...
