摘要： A gate driving circuit for driving a voltage-driven switching device is provided with a current limiting circuit for limiting a gate current ig that flows into a gate terminal through a gate resistor at turn-on to a current limit value IL which defines an upper limit value. The current limit value IL is set at a value which is larger than a gate current value I2 at turn-on of the switching device during a period when the Miller effect occurs but is smaller than a gate current value I1 at a point in time when a main current begins to flow at turn-on in a case where the gate current ig is not limited by the current limiting circuit. This arrangement makes a variation in a collector current of the switching device moderate at turn-on thereof when the collector current begins to flow, thereby reducing high-frequency noise.

摘要： A measurement value judgment method for comparing measurement values from sensors provided at various locations of a system with pre-set reference values, and judging, based on the results of the comparison so made, whether the system is normal or abnormal, comprises the steps of judging a quantity of state relative to the load on the system and changing the reference values in response to the results of the judgement, the thereby judging accurately whether or not the system and sensors are in an abnormal status by accurately identifying the operating state of the system.
