摘要： An apparatus is provided to drive a voltage controlled switching element having a conduction control terminal. In the apparatus, it is determined whether or not voltage at the conduction control terminal is at a first voltage which is lower than a second voltage and which is equal to or more than a threshold voltage. The second voltage is a voltage provided when the switching element is in a normal on-state thereof. The threshold voltage is voltage at which the switching element is switched on. When it is determined that the voltage at the conduction control terminal is at the first voltage, the switching element is forcibly switched off.

摘要： A drive system has a low voltage system, a high voltage system, and a transformer. The high voltage system has drive units which correspond to power switching elements. A capacitance in the high voltage system serves as a flouting power source which supplies electric power to each of the drive units. An output voltage of a secondary side coil of the transformer is supplied to the capacitance. A comparator compares the output voltage at the secondary side coil of the transformer with a threshold value. A switching speed change part changes the switching speed of each of the power switching element based on the comparison result of the comparator.
