dc.description.abstract | In this article, a three-level current-mode boost converter with a fully state-based phase selection (FSPS) technique is presented. The proposed FSPS technique selects the operation phase adaptively to ensure the voltage across the flying capacitor (V-CF) to V-O/2 and changes the operation mode of a three-level boost converter (3L-BST). It enables the flying capacitor to be charged or discharged consecutively at the same duties every switching period and the operation mode to be changed smoothly. Therefore, 3L-BST improves the V-CF calibration speed with the stable startup and removes the sub-harmonic oscillation of the inductor current caused by the V-CF calibration, and the output voltage fluctuation is alleviated in the mode transition region. In addition, to compensate the stability of both valley and peak current-mode control for a wide output voltage range, the proposed FSPS technique adopts the adaptive slope generator (ASG) of which the slope can be changed from negative to positive. This work, fabricated in a 0.18-mu m bipolar-CMOSDMOS (BCD) process, occupies an area of 5.51 mm(2). The peak efficiency of the proposed 3L-BST is 95.3%, with an input range of 2-6 V, an output range of 5-32 V, and a 0.5-A maximum load current. The inductor current ripples are 1.45x smaller than prior VCF calibration techniques. The total startup time is 490 mu s. | - |
