摘要： The discharge control device for a power conversion system performs discharge control to discharge a capacitor parallel-connected to the input side of the power conversion system including a plurality of pairs of high-side and low-side switching elements connected in series and each controlled by a drive unit, by turning on the high-side and low-side switching elements of one of the pairs at the same time. At this time, the discharge control device inhibits an ON command from being inputted to the drive units for the high-side and low side switching elements of the other pairs.

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 discharge circuit for discharging a capacitor disposed in a power conversion circuit. The discharge circuit includes: a conduction path connecting the power conversion circuit and input terminals; plural resistors disposed in the conduction path, dividing voltage difference between voltage at the input terminal and reference voltage; a connection path connecting a pair of conduction paths; a switch disposed in the connection path, which opens and closes the connection path, the switch being controlled electrically; and a control unit that controls the switch to be opened or closed, the control unit controls the switch to be closed in order to make a closed loop circuit including the capacitor and the connection path. The connection path is disposed between the pair of conduction paths to include at least one resistor of the plurality of resistors in the closed loop circuit when the switch is closed by the control unit.
