该论文提出了一种多核隔离DC-DC转换器，采用嵌入式磁芯变压器，实现了2W输出功率和53.2%的峰值效率，并满足CISPR-3电磁兼容标准。解决了传统集成隔离DC-DC转换器输出功率有限（约1W）的问题。
Hefei CLT Microelectronics, Hefei, China 1 2 Integrated isolated DC-DC converters, using either on-chip [1-4] or package transformers [5-7], have been developed to minimize size and cost while achieving isolation ratings above 5kV and delivering around 1W of output power. As shown in Fig. 32.5.1, these converters typically consist of an inverter, a transformer, and a rectifier. The inverter oscillates at frequencies in the tens-of-MHz range due to the limited inductance of the size-constrained transformer to transfer power, and it is switched on and off by a PWM signal at around 1MHz to regulate the output voltage. However, this topology faces several challenges: 1) PWM control introduces severe conducted electromagnetic interference (EMI) (in the 150kHz to 30MHz range) that is caused by the discontinuous input current, and also leads to significant output voltage ripples due to discontinuous current delivery. While an EMI
