In order to integrate a soft-switching power supply on a chip, extension of operating frequency of soft-switching power supply to a higher frequency was developed. In this research, a novel protection circuit was developed in order to prevent destruction of transistor due to extremely high switch voltage during the transient state. A detection circuit was developed in order to acquire operating state of high frequency soft-switching power supply to digital control circuit. A novel gate driving scheme was proposed in order to reduce power dissipation at gate port of transistor which becomes unignorable in the high frequency operation.

为了将软开关电源集成到片上，将软开关电源的工作频率扩展到更高的频率。在这项研究中，为了防止晶体管在暂态时由于极高的开关电压而损坏，开发了一种新型的保护电路。为了将高频软开关电源的工作状态采集到数字控制电路中，研制了一种检测电路。提出了一种新颖的栅极驱动方案，以降低晶体管在高频工作时不可忽视的栅极端口处的功耗。
