Research on Voltage Sharing Control Technology of Rectifier Stage of High-Power High-Frequency Auxiliary Power Supply
The unbalanced distribution of high power and high frequency auxiliary power supply will greatly affect the stability of power grid operation voltage,therefore,a voltage sharing control technology of rectifier stase of high-power high-frequency auxitiary power sup-ply is proposed.According to the single-stage binary logic switch function and Kirchhoff voltage law,the state of power supply voltage is obtained.Clarke transform is used to obtain the topological relationship between high-power high-frequency auxiliary power supplies and generate the voltage control law of power supply rectification level.The control scheme of the discrete direct power of the power supply is determined,the power of each module of the power supply is reallocated in real time,the compensation results of the unbalanced volt-age are obtained,and the voltage sharing control of the rectifier stage of the high-power high-frequency auxiliary power supply is real-ized.The experimental results show that the proposed technology has good control effect and wide application range.
