Automatic Control Method for DC Power Output Based on Three-phase Rectifier Bridge
Due to the influence of internal resistance of the power supply and load changes,the output of DC power supply will experience varying degrees of fluctuations.Therefore,this article proposes a research on automatic control method for DC power output based on three-phase rectifier bridge.On the basis of constructing a three-phase bridge rectifier circuit topology that includes the power supply,diode bridge,load section,and filtering section,targeted setting of capacitance and inductance values in the three-phase bridge rectifier circuit topology is carried out.By using feedback control strategy and combining with the actual operating conditions of DC power supply,adaptive control of its output is achieved.In the test results,the fit between the output voltage and input voltage parameters under the designed control method is the highest,and the corresponding control effect is the best.
