Title:
POWER CONVERSION DEVICE AND POWER CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JP2018098850
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power conversion device and a power conversion system which are capable of controlling an output voltage with high precision irrespective of flow of a cross current.SOLUTION: A PWM rectifier 10a (power conversion device) is one of a plurality of PWM rectifiers 10 which are connected to a load 3 and which are connected in parallel with one another. The PWM rectifier 10a includes a converter 13 that converts an AC current to a DC current, and a control unit 15 that generates an active current command value Id2 which is a current command value for the converter 13. The control unit 15 is configured to generate a next active current command value Id2 for the converter 13 of the PWM rectifier 10a, on the basis of a DC current detection value Idc1 output from the own PWM rectifier 10a and a DC current detection value Idc2 output from another PWM rectifier 10b that is connected in parallel with the PWM rectifier 10a.SELECTED DRAWING: Figure 2
