该论文提出了一种单电感双极性输出（SIBO）转换器，采用简洁的PWM控制，实现了94.5%的峰值效率和3.99W/mm²的功率密度，用于驱动AMOLED显示屏。解决了传统双电感方案体积大、效率低的问题。
Hefei CLT Microelectronics, Hefei, China *Equally Credited Authors (ECAs) 1 2 DC-DC converters with bipolar outputs are widely used to drive AMOLED displays in battery-powered electronic devices. To prolong the battery life and meet the demand of increasing display dimensions, these converters should have high efficiency and high driving capability while minimizing PCB footprint. Compared with the solution using one boost converter and one inverting buck-boost converter with two inductors [1], the single-inductor bipolar-output (SIBO) converters [2] only require one inductor to generate both positive output (VOP) and negative output (VON), making them highly desirable for reducing form factor and cost. A flying capacitor is further introduced to the SIBO topology in [3] to reduce voltage stress on power transistors and inductor current for efficiency improvement. However, the three-phase control, which
