摘    要:DC-DC变换器工作在额定负载时,输入电压会出现扰动。工作在额定输入电压时,负载电阻也会发生突变。为了实现宽电压输入,保证变换器具有较高的输入电压调整率和负载调整率,设计了自动切换与控制策略。根据Buck-Boost型DC-DC变换器的工作特点,计算出开关的导通与关断时间点,从而精确地控制开关动作。基于并行运算和组合逻辑,在Matlab中搭建了模型,并进行了仿真和试验验证。结果表明,提出的控制方法能够有效地克服负载电流突变和输入电压扰动对变换器性能的影响。

关 键 词:DC-DC变换器  并行运算  组合逻辑  调整率

Abstract:The releasing progress of microsatellite on orbit is simulated by the free-fall method. The releasing speed is tested by high-speed photography,realeasing attitude and shock response are tested by the testing system assembled in the satellite . By this testing method can test the releasing speed、the releasing attitude and the releasing shock response simultaneously.
