| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | GaN-Gate Injection Transistor(GIT) Bi-directional Switches (BDSWs) is capable of the low on-resistance operation as compared with typical switching devices, and by employing GaN GIT-BDSWs in the switching circuit, the reduction of a number of the devices and a switching loss are expected. In this study, we propose the equivalent-circuit-model for GaN GIT-BDSWs in order to design switching circuits employing these devices. Although the GIT-BDSWs have four terminals, the equivalent-circuit-model for those consists of three terminals, one gate and two sources, because one gate keeps opened during switching the other gate in the typical operation. The circuit elements in the equivalent-circuit-model consist of one current source and three capacitances. The parameters of the circuit elements are extracted with high accuracy due to the extraction form the switching characteristics. When the switching waveforms and losses in the chopper circuit are calculated by this model, the accuracy of the calculation for the experiments exceeds 90%. | |
