POWER SEMICONDUCTOR MODULE AND METHOD FOR STABILIZING THEREOF |
摘要 |
Provided is a stabilizing circuit structure using a sense field effect transistor (sense-FET). A power semiconductor module includes a depletion-mode field effect transistor (D-mode FET) and the sense FET that has same structure as the D-mode FET and varies in area. Also the power semiconductor module includes not only an enhancement-mode field effect transistor (E-mode FET), but also the stabilizing circuit including circuit elements such as a resistor, a capacitor, an inductor, or a diode. |

1. A power semiconductor module comprising:
a depletion-mode field effect transistor comprising a gate, a drain, and a source, the depletion-mode field effect transistor being served as a main transistor for power switching; a sense field effect transistor configured to share the gate and the drain of the depletion-mode field effect transistor, the sense field effect transistor having current driving ability less than that of the depletion-mode field effect transistor; an enhancement-mode field effect transistor configured to connect the drain to a floating node that is the source of the depletion-mode field effect transistor so as to form a cascode structure, the enhancement-mode field effect transistor being configured to drive the depletion-mode field effect transistor; a first stabilizing circuit connected between the floating node and a source of the sense field effect transistor to perform voltage stabilization of the floating node; and a second stabilizing circuit connected between a source of the enhancement-mode field effect transistor and the source of the sense field effect transistor to perform voltage stabilization of the floating node. |
