Filed: 2018-07-18
Abstract: To suppress current concentration on a sense IGBT without delay in detecting a short-circuit current in a transient state.SOLUTION: An IGBT 10 is provided with a voltage divider circuit composed of voltage divider resistors Rdiv1 and Rdiv2 connected in series to the gate terminal and emitter terminal of a main IGBT 11, and connects a connection point of the voltage dividing resistors Rdiv1 and Rdiv2 to the gate terminal of a sense IGBT 12. When a voltage applied to the gate terminal of the main IGBT 11 is equal to a threshold voltage of the main IGBT 11, a voltage applied to the gate terminal of the main IGBT 11 is divided so as to become a threshold voltage of the sense IGBT 12. Thus, when a gate signal for turning on is applied to the gate terminal G of the IGBT 10, the currents of the main IGBT 11 and the sense IGBT 12 rise at the same time, such that there is no delay in detecting a short-circuit current and the current concentration on the sense IGBT 12 is suppressed.SELECTED DRAWING: Figure 1
