Abstract

See full text

A power electronic device on a direct-current side of a photovoltaic system, and a test system and a control method therefor, achieving a simple, fast, and low-cost functional test on the power electronic device during a production process or a troubleshooting process of the power electronic device on the direct-current side of the photovoltaic system. The power electronic device is used for detecting a fluctuation of an electric signal parameter of an input end of the power electronic device; when the fluctuation meets a preset condition, the device is switched from a limited output state to a non-limited output state; the fluctuation of the electric signal parameter of the input end is generated by applying a disturbance to the input end of the power electronic device on the direct-current side of the photovoltaic system by a direct-current power supply having a disturbance output.
