一种新的开关电源变换器控制策略及其仿真实现

摘要

Aiming at the traditional DC converter voltage control strategy of load voltage slow response speed disadvantage, a new control strategy is proposed, the programme to BUCK converter as the foundation, power circuit and V2C feedback control loop, the simulation results show that this scheme can has a fast response speed and has good anti jamming ability for mutational load and input voltage.%针对传统变换器响应速度慢、无法有效适应负载突变的缺点,提出了一种新的控制策略.该方案以BUCK变换器为模型,在目前较为流行的V2 (voltage-voltage)控制策略的基础上,在内反馈环中采用电感电流与输出电压相加作为反馈量,以此实现高效、快速的信号转换.仿真结果表明该方案能够对负载突变具有较快的响应速度,并且具有良好的抗干扰能力.
