| Research Abstract |
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.
