基于数字控制Buck电路的DC-DC电源变换器仿真研究
Simulation Study on the DC-DC Power Source Converter Based on Digital Control Buck Circuit
摘要
Abstract
The possibility of digital control application in middle and low power DC-DC conversions are more and more outstanding. Based on the digital control Buck circuit,a power source convert circuit of 30~60 V DC input to 24 V DC output was proposed. And the feasibility of the proposed Buck circuit was verified by the software simulation. During the design of the DC-DC power source convertor,the state space average method was used to establish the basic circuit model,and the S phase voltage feedback control circuit,as well as the PID compensator was applied to achieve the stable efficiency of DC-DC converting. The conclusions can provide certain references for the design and optimization of DC-DC converting circuit.关键词
