飞电容变换器的自然电压平衡特性是其吸引人的特点。目前已有的电压平衡动力学分析研究方法都是基于重频域变换（傅立叶变换、贝塞尔函数等），且算法化程度较高，难以在日常工程实践中应用。建议的时域方法是对连续切换区间的分段解析解进行拼接。五电平单支路转换器的小参数分析为平均电压平衡动力学提供了物理上有意义，简单和准确的表达式，从而深入了解直流和交流PWM的参数，载波频率和调制策略影响。
The attractive feature of a flying capacitor converter is the natural voltage balance property. The reported voltage balance dynamics analytical research methods are based on heavy frequency domain transformations (Fourier transform, Bessel functions etc) and are rather algorithmic and difficult to use in an everyday engineering practice. Suggested time domain approach uses stitching of piece-wise analytical solutions for consecutive switching intervals. The small parameter analysis of a five-level single-leg converter yields physically meaningful, simple, and accurate expressions for average voltage balance dynamics giving an in-depth insight into parameters, carrier frequency, and modulation strategy impact for both DC and AC PWM.
