ABSTRACT

This paper studies the bidirectional DC / DC converter of power supply system based on the IOT, and discusses the basic principle and types of DC / DC converter; The buck / boost bidirectional DC / DC converter is proposed, and the inductance parameters are designed. The buck / boost simulation experiment is carried out through the proposed inductance algorithm. The simulation data under boost mode and topology simulation data under buck mode are tested; The results show that when the input voltage is 150V, the steady-state values of the output voltage and the flying capacitor voltage remain unchanged when the circuit is in a stable mode. The proposed topology can achieve a high step-down ratio without limiting the duty cycle, and the flying capacitor voltage is half of the output voltage. Through the analysis of the two modes of topology voltage rise and fall, it can be seen that this topology can achieve a high step-down ratio and two-way flow of energy. Therefore, this topology can realize high-power operation. The above circuit data changes, and the results are well verified in the stability of dynamic response.
