Abstract

The invention provides a reliability test system suitable for a vehicle-specification-level power / electronic device. The reliability test system comprises a plurality of motor controllers, wherein aninput end of each motor controller is electrically connected with a programmable power module, an output end of each motor controller is electrically connected with a load, and the motor controller, the programmable power supply modules and the loads form an electrical loop of the vehicle-specification-level power / electronic device to be tested. The reliability test system further comprises a central control system, wherein the central control system is in communication connection with the programmable power supply modules and the motor controllers, and the central control system is used for controlling the motor controllers, monitoring a test process and recording test data. The reliability test system can adjust the number and the connection mode of the motor controllers in the test system according to different test requirements and tests, is simplified, and has the advantages of configurability, high efficiency and high compatibility.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a reliability testing system suitable for vehicle-level power / electronic devices. Background technique [0002] In the field of electric power, power electronics technology is a technology that uses electric / electronic devices (such as transistors, thyristors, etc.) to transform and control electric energy, and is widely used in general industry, transportation, power system, electronic device power supply, household appliances and other industries middle.
