摘要：
Taking single-inductor dual-output (SIDO) Boost converter in continuous conduction mode (CCM) as the research object, the working principle of CCM SIDO Boost converter controlled by common-mode voltage and differential-mode voltage (CMV-DMV) is analyzed in detail. The time-average equivalent circuit modeling approach is used to derive the transfer functions, such as control to output, output impedance and cross-regulation impedance, and so on. By establishing the closed-loop small signal model of CMV-DMV controlled CCM SIDO Boost converter, the cross-regulation characteristics in different output voltage levels are discussed by bode diagram in frequency-domain. The results show that, for CMV-DMV controlled CCM SIDO Boost converter, the cross-regulation of high-voltage output to low-voltage output is smaller than that of low-voltage output to high-voltage output when the two output voltages are not equal, while the cross-regulation of the first turn-on output branch to the second one is bigger than that of the second output branch to the first one when the two output voltages are equal. Finally, the correctness of the theoretical analysis is verified by the experimental results. © 2019, Electrical Technology Press Co. Ltd. All right reserved.
