| Abstract: | Basing on the control principle of direct power,the influence of the instantaneous active power and reactive power on the three phase PWM control system is analyzed,and the instantaneous active power and reactive power according the coordinate transformation theory is obtained.Furthermore,in order to reduce errors,the current compensation was introduced in the analysis of the instantaneous active power.Finally the traditional switching table was used to control the system.The simulation results further indicate this method is reasonable and valid. |
| Keywords: | PWM rectifying circuit direct power control instantaneous power |
