Claim of US Patent No. 9,279,861

1. An apparatus for testing switching of a power semiconductor module, comprising:
a power semiconductor module including a plurality of power semiconductor devices corresponding to a plurality of phases to
test a switching operation of a corresponding power semiconductor device;

a power supply unit supplying power to the power semiconductor module;
a relay switching unit including a plurality of relay switch devices that connects or disconnects between the power semiconductor
module and the power supply unit according to a relay control signal; and

a control unit controlling the relay switching unit to test on/off characteristics of the plurality of power semiconductor
devices simultaneously,

wherein the control unit controls the on/off of the relay switching unit connecting between the power semiconductor module
and the power supply unit through various paths to supply power to the corresponding power semiconductor devices so as to
test the on/off operation of the corresponding power semiconductor device.
