摘要： The present invention lowers energy loss while at the same time enhancing the responsiveness of a steering control system. When a steering controller is operated rapidly, the aperture area of a steering flow control valve 4 rapidly increases, and the differential pressure (Pp′-PL) across the steering flow control valve 4 rapidly decreases. When the differential pressure (Pp′-PL) across the steering flow control valve 4 rapidly decreases, a flow control valve 6 is biased by the spring force of a spring 6f and quickly moves to the side of a valve position 6b to increase the differential pressure (Pp′-PL) and make it correspond to a set pressure. Thus, the pressure oil of a surplus flow α, which up to this point has been flowing to a discharge oil line 7, is quickly supplied from the flow control valve 6 to a steering hydraulic cylinder 5 via the steering flow control valve 4. Thus, an output Q′ starts quickly relative to an input St.

摘要： When a driving unit (100) charges gate input capacitance (6) of an IGBT (7), the gate input capacitance (6) accumulates electric charges which are accumulated therein when the driving unit (100) discharges the gate input capacitance (6). Therefore, it is possible to reduce the amount of electric charges to be supplied to the gate input capacitance (6) by the driving unit (100) until the charge of the gate input capacitance (6) is completed. As a result, it is possible to reduce the required power capacity of a control power supply (15a). Further, since the electric charges accumulated in the gate input capacitance (6) are effectively used, it is possible to ensure power savings of a semiconductor device. Thus provided are a semiconductor device and a method of driving a transistor, in which electric charges accumulated in gate input capacitance of an insulated gate transistor are effectively utilized, to reduce required power capacity of a power supply for driving the transistor and ensure power savings of the semiconductor device on the whole.
