Abstract:

Random switching modulation technology can reduce the electromagnetic interference of switching power supply. Chaos is a random signal generated by a deterministic system that can be used for a control signal modulated by random switching of switching power supplies. Taking the chaotic output of Cai’s circuit as the signal source, the software implementation method for controlling the switching modulation signal of switching power supply is given. The generated chaotic modulation switching signal is applied to the boost circuit to verify the effect of chaotic switching modulation technology in reducing the level of electromagnetic interference. The computer simulation results show that the chaotic switching modulation signal generated by using the chaotic output of the Cai circuit as the signal source can reduce the electromagnetic interference level of the switching power supply.
