为了提高开关电源的功率密度，需要低损耗的小型变压器。提高驱动频率是变压器小型化的有效策略；然而，这种策略增加了损失。在本文中，我们研究了利用磁通路径控制 (MPC) 技术减少导体嵌入式平面变压器产生的损耗的策略。采用MPC技术的导体嵌入式平面变压器的交流电阻小于传统导体嵌入式变压器的交流电阻。在这项研究中，我们证明我们提出的变压器的 <inline-formula> <tex-math notation="LaTeX">${Q}$ </tex-math></inline-formula> 因子优于传统变压器的 <inline-formula> <tex-math notation="LaTeX">${Q}$ </tex-math></inline-formula> 因子。
To improve the power density of switching power supplies, a small transformer with low loss is required. Increasing the drive frequency is an effective strategy for miniaturizing the transformer; however, this strategy increases the losses. In this article, we investigate strategies to reduce the losses arising from conductor-embedded planar transformers using magnetic flux-path control (MPC) technology. The ac resistance of a conductor-embedded planar transformer that uses the MPC technology is less than the ac resistance of a conventional conductor-embedded transformer. In this research, we prove that the <inline-formula> <tex-math notation="LaTeX">${Q}$ </tex-math></inline-formula>-factor of our proposed transformer is superior to the <inline-formula> <tex-math notation="LaTeX">${Q}$ </tex-math></inline-formula>-factor of the conventional transformers.
