摘要
提出一种大功率中压直流电源的设计方法,采用了智能编程DSP三相有源功率校正控制技术及LLC谐振变换技术,整流滤波采用三相三开关三电平的有源校正电路。通过测试及试验验证,此电源具有高PFC值、低THD值、高效率、电磁干扰小的特点。
A high-powermedium-voltage DC power supply is designed,adopting the intelligent programming DSP three-phase active power correction and control technology and the LLC resonant conversion technology,and rectifying filter uses the three-phase three-switch three-level active correction circuit.It is verified that power supply features high PFC value,low THD value,high efficiency and little electromagnetic interference through the test.
