基于部分功率调节的高调压速率DC/DC变换器OACSTPCD

The telecommunication power supply applied in 5G base stations can save energy consumption by reducing the output voltage when the equipment works in standby state.Nevertheless,frequent and rapid output voltage regulating of the converters is challenging.To solve this problem,the concept of partial power conversion was adopted in the design of power supply converters.A partial voltage regulating circuit was added at the output side of the converter,and fast output voltage regulating was realized with control of outer voltage loop,inner current loop,load current feedforward and output voltage feedforward loop.At the same time,higher energy conversion efficiency was guaranteed.A 1 kW DC/DC converter was built and verified the effectiveness of the proposed topology and control strategy.
