为了将软开关电源集成在芯片上，将软开关电源的工作频率扩展到更高的频率。在本研究中，一种新颖的保护电路，以防止晶体管的破坏，由于极高的开关电压在瞬态。为获取高频软开关电源的工作状态，为数字控制电路设计了一种检测电路。为了降低高频工作时晶体管栅极端的功耗，提出了一种新的栅极驱动方案。

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.
