Calculation and Analysis of DC Side Output Voltage of Dual Three-phase Rectified DC Generator Considering Parasitic Parameters of Filter Capacitor
摘要
Abstract
The DC power supply system with pulse power load has been widely used in electric vehicles,ships,aviation and other fields.When there is a sudden change in pulse load,the voltage at the rectified DC generator terminal will change accordingly,which will have a negative impact on the stability of the entire power supply system.At this time,the filter capacitor plays a key role.Generally,electrolytic capacitors are used as filter capacitors in DC power supply systems.The equivalent series resistance(ESR)of parasitic parameters exists in electrolytic capacitors,which can cause the distortion of the output voltage waveform and the change of the voltage magnitude.Therefore,this article proposes a method for calculating the instantaneous voltage of the dual three-phase rectified DC generator with pulsed load considering the filter capacitor's parasitic parameter ESR.Firstly,this article establishes an equivalent transient mathematical model of the dual three-phase rectified DC generator with pulsed power load considering the filter capacitor's parasitic parameter ESR.Secondly,by comparing the transient finite element simulation of the dual three-phase rectified DC generator with the load mutation experiment,the necessity and feasibility of the transient voltage calculation method for the equivalent model load mutation of the generator considering the filter capacitor's parasitic parameter ESR proposed in this paper are verified.Finally,the influence of the filter capacitor's C and its parasitic parameter ESR on the DC side voltage of the dual three-phase rectified DC generator is analyzed.The results indicate that the equivalent model established in this article has high accuracy,and considering the filter capacitor's parasitic parameter ESR for DC voltage measurement of rectified DC generators is of great significance for improving power quality of the entire DC power supply system.关键词
