Japan, Sept. 18 -- HITACHI INDUSTRIAL EQUIPMENT SYSTEMS CO LTD has got intellectual property rights for 'POWER CONVERTER AND POWER CONVERSION METHOD.' Other related details are as follows:
Application Number: JP,2023-135762
Category (FI): H02M7/48@K,H02M7/48@M
Stage: PROBLEM TO BE SOLVED: To provide a power converter and a power conversion method that effectively utilize a power semiconductor with an appropriate life by suppressing damage to the power semiconductor when an operation condition at the time of facility operation is set.SOLUTION: A power converter 100 includes a rectifier unit 200 that inputs an AC voltage from an AC power supply 1000 and outputs a DC voltage, an inverter unit 4 that converts the DC voltage output from the rectifier unit into the AC voltage, a control unit 7 that controls trial operation of the inverter unit 4 based on a predetermined operation condition, and a damage amount processing unit 9 that calculates and accumulates a damage amount of the inverter unit 4 during a trial operation period of the inverter unit 4 by the control unit 7, and acquires an operation result of the inverter unit 4 based on the accumulated damage amount.SELECTED DRAWING: Figure 1 (Grant)
