Abstract
The mentioned article (Liu et al., 2023) proposed the frequency-domain-based modified impedance tuning analysis method and its demonstration in designing a Class-Phi(2) dc-dc converter with low dv/dt at 50% switching duty cycle. However, there are two typos during deriving the critical duty cycle and equivalent switching frequency of the established circuit model. In this article, we presents the corrections to avoid possible misleading to the readers.
