Abstract
A power conversion device which is a test target performs DC voltage conversion between a primary side DC terminal and a secondary side DC terminal. A first connection member electrically connects a testing power supply and the primary side DC terminal serving as an input side of the test target. A second connection member electrically connects the primary side DC terminal and the secondary side DC terminal of the power conversion device to transmit active power output from the secondary side DC terminal to the primary side DC terminal to be a part of active power input to the primary side DC terminal.
Claims14
A system to test a power conversion device, comprising:
- at least one power conversion device to serve as a test target,
- each power conversion device to perform DC voltage conversion between a primary side DC terminal and a secondary side DC terminal for inputting and outputting DC voltage;
- a testing power supply for the test target;
- a first connection member to electrically connect the testing power supply and an input side of the test target;
- and
- a second connection member to electrically connect an output side of the test target and the testing power supply for transmitting active power output from the output side of the test target to the input side of the test target.
A method for testing a power conversion device, at least one power conversion device being a test target in the method, wherein
- the power conversion device performs DC voltage conversion between a primary side DC terminal and a secondary side DC terminal for inputting and outputting DC voltage, and
- when the test target is tested, from a testing power supply electrically connected to an input side of the test target by a first connection member, the test target, with an output side of the test target and the input side electrically connected via a second connection member, is supplied via the first connection member with active power smaller than active power passing through the test target.
