A method for operating a compressor, which supplies an internal combustion engine that is assigned to the compressor at its output end with air compressed to a boost pressure, in which the boost pressure is reducible by releasing the compressed air at least partially via a pressure release valve. The air released via the pressure release valve is used for driving a compressor wheel of the compressor.
