| 摘 要： | 针对航空地面电源车现行励磁调压系统存在的动态响应速度较慢以及直流保障时输出电压不稳定等问题,提出在其励磁调压系统中加入直流电源控制与电压反馈组成双闭环控制系统的方案;针对所选用的电流滞环控制方案存在的开关频率不稳定及由此带来的输出电压谐波含量高、容易损坏功率开关管等问题,提出用变环宽恒频电流滞环控制方案,使系统在保持快速动态响应速度的同时,实现了开关频率的固定。仿真和实验结果验证了所提方案的可行性。

| Abstract: | Aiming to the problems existing in the excitation voltage adjustment system of aircraft power support van such as slow dynamic response speed and the poor output voltage stability,it proposes a scheme of introducing DC supply control to the excitation voltage adjustment system in order to form a double closed loop control system.For eliminating the unstable stability of switch frequency in hysteresis current control method which may cause high harmonics of output voltage and easy-damage of power switch devi... |
