摘要： A power conversion device generates drive command signals for switch elements of multiple phases, the drive command signals designed to control connecting and disconnecting operations of the multiple phase switch elements in such a way that a direction of a current change attributed to a connecting or disconnecting operation of one switch element and a direction of a current change attributed to a connecting or disconnecting operation of another switch element are opposite to each other. Furthermore, the power conversion device corrects output timings of the drive command signals to be outputted to the switch elements so as to synchronize connecting and disconnecting timings of the switch elements with each other.

摘要： A power conversion apparatus includes a plurality of power modules, a plurality of capacitors and a bus bar. Each of the power modules has a direct current terminal section and an alternating current terminal section. Each of the power modules is configured and arranged to convert a direct current inputted from the direct current terminal section into a respective phase of a multiple-phase alternating current and to output the multiple-phase alternating current to the alternating current terminal section. Each of the capacitors is arranged with respect to a corresponding one of the power modules. The bus bar forms an inter-phase current path between the power modules that are adjacent and forms an intra-phase current path between one of the power modules and a corresponding one of the capacitors such that an impedance of the inter-phase current path is smaller than an impedance of the intra-phase current path.

摘要： The present invention relates to an automotive transmission for an industrial vehicle. The main shaft of the transmission gear is hollow and internally splined to be slidable along and synchronously rotatable with an externally splined input shaft. Upon removal of a snap ring which holds at least two gears and a synchronizer (disposed between the gears) in place on the main shaft and the removal of a lock pin which interconnects the main shaft and the input shaft, the main shaft can be slid toward the clutch allowing the gears and synchronizer to be slipped, one by one, off the end of the main shaft and readily replaced with new units.
