1. A synthetic test circuit for testing a submodule performance in a power compensator, comprising:
- a submodule test unit which includes a capacitor and is an object of testing the submodule performance;
a current source connected to the submodule test unit to supply a voltage to the capacitor of the submodule test unit such that a preset charging voltage is stored in the capacitor in order to operate the submodule test unit; and
a controller configured to test the submodule performance of the submodule test unit using the stored preset charging voltage,wherein the submodule test unit is configured to store the voltage supplied by the current source in the capacitor as the preset charging voltage before the test of the submodule performance, and generate a test current using the preset charging voltage stored in the capacitor, andwherein, if loss is generated in the test current during the test of the submodule performance, the current source supplies an extra voltage to the submodule test unit.

Abstract
A synthetic test circuit for testing a submodule performance in a power compensator includes a submodule test unit which is an object of testing the submodule performance, a current source and a controller. The current source is connected to the submodule test unit to supply a voltage to the submodule test unit such that a charging voltage having a capacity set in the submodule test unit is stored in order to operate the submodule test unit. The controller is configured to perform control to perform a submodule performance test of the submodule test unit using the stored charging voltage.

13. A test method of a synthetic test circuit for testing a submodule performance in a power compensator including a submodule test unit which includes a capacitor and is an object of testing the submodule performance, a current source connected to the submodule test unit and a controller, the test method comprising:
-
supplying, by the current source, a voltage to the capacitor of the submodule test unit such that a preset charging voltage is stored in the capacitor in order to operate the submodule test unit; storing, by the submodule test unit, the voltage supplied by the current source in the capacitor as the preset charging voltage before the test of the submodule performance; operating, by the controller, the submodule test unit using the stored preset charging voltage; generating, by the submodule test unit, a test current based on the preset charging voltage stored in the capacitor; testing, by the controller, the submodule performance using the test current; and if loss is generated in the test current during the test of the submodule performance, supplying, by the current source, an extra voltage to the submodule test unit. - View Dependent Claims (14, 15)
