| 摘 要： | 在数控双向DC/DC变换器的平均电流控制中,由于受数字系统采样频率的限制,存在电流断续时无法控制的问题.本文基于F2407A DSP控制系统,提出了一种在电流断续时采用开环控制的策略.通过采样输入输出电压以获取电感的平均电流,从而代替了实际的采样电流,以进行PI调节.实验结果表明,当电感电流断续时,该控制策略能很好地实现电路的恒流控制.

| Abstract: | In average current control of directional digital DC/DC converter,a problem that the output average current can not control well when inductance current is in an intermittent condition because of limited by digital sampling frequency.This paper proposes an opening loop control scheme based on F2407A DSP system.The average inductance current can be calculated by input voltage and output voltage to use in PI regulator.Experimental results prove that this scheme can achieve constant current control when inductance current is in a discontinuous condition. |
