The control tactics of space voltage vector are investigated , and the simplified algorithm which judges the sector location of reference vector and calculates switch operation time is put forward . by analyzing the current hysteresis control , the relation between switch frequency , and hysteresis bandwidth and input inductance of pwm rectifier is deduced . by applying instantaneous power theory , the principle of pwm rectifier power control is analyzed , and the direct power control by matlab toolbox through estimating active power and reactive power with virtual flux is realized , and the simulation results prove that it is correct
