Title:
TEST SYSTEM AND TEST METHOD FOR POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/092911
Kind Code:
A1
Abstract:
A power conversion device (100) to be tested performs DC voltage conversion between primary-side DC terminals (1a, 1b) and secondary-side DC terminals (2a, 2b). A first connecting member (PL1) electrically connects to each other a power supply (201) for testing, and the primary-side DC terminals (1a, 1b) on the input side of the subject to be tested. A second connecting member (PL2) electrically connects to each other the primary-side DC terminals (1a, 1b) and the secondary-side DC terminals (2a, 2b) of the power conversion device (100), thereby transmitting, to the primary-side DC terminals (1a, 1b), effective power (Po) outputted from the secondary-side DC terminals (2a, 2b), and making the effective power as a part of effective power (Pi) to be inputted to the primary-side DC terminals (1a, 1b).
