| Abstract: |
| A digital battery simulator based on power electronic technology and DSP is designed，which takes the three-phase VSC （Voltage Source PWM Converter） as the main topology of its hardware，being capable of simulating the exterior characteristics of various battery types，such as lead-acid battery，lithium battery，fuel cell，Vanadium redox flow battery，PV cell，and applies the 3-order dynamic battery model and the double-loop control strategy to guarantee its high accuracy and fast response. The flowchart of software design is given. The simulative and experimental results show that，the voltage control error of the designed battery simulator is within ± 0.2 V，its simulation accuracy is high，its voltage ripple is small，its tracking speed is fast and its control effect is ideal. |
