Abstract

A power conversion device having inverter units (1 to N) connected in parallel , wherein not only cross - current caused by gate signal timing, but also cross-current caused by switching element (Tu1 to TuN ; Tx1 to TxN ) characteristics errors as well as gate signal delay interference caused by ,e.g . , a physical configuration as a result of the distance or shape of a transmission circuit are suppressed . A specified gain is multiplied by a proportional amp (P) , using as the cross - current the deviation between an inverter unit output current command value (IinvUdet/N) and an inverter unit output current detection value (IinvUNdet) . Integral amps (I1 , I2 ,I3 , I4 ) are provided each time each switching element is turned ON or OFF, and the cross - current generated after the switching elements have turned ON or turned OFF is integral - amp processed and updated . The outputs of the proportional amp and the integral amps are added and a rising gate delay command value (DelayrefU) and a falling gate delay command value (DelayrefD) are output . Figure 2
