The invention belongs to the field of power converter control, and relates to a novel fixed frequency model predictive current control method with a dynamic variable weight. The method controls a system according to an equivalent switching circuit of a triple converter and an integrated control theory. Traditional fixed frequency model predictive current control accurately calculates a voltage vector needed at a next moment according to a discrete mathematical model of the system, thereby achieving the characteristic of fast response in a dynamic process.
