Harmonic Amplitudes Calculation Method and Simulation of Diode-bridge Rectifier's Output Current

Taking the three-phase uncontrolled diode-bridge rectifier of a certain style armored vehicle's power supple system as research object, a practical method to calculate the harmonic amplitudes of rectifier's DC-side output current is theoretically analyzed with the detailed calculation formulas are given. Based on MATLAB, the rectifier's circuit model is constructed. The comparison of simulation and calculation results shows that the analyzed method in this paper has high-accuracy, and is simple enough for engineering application.
