摘要
The power startup of SAR satellite load has the characteristics of heavy power and high frequency instantaneous pulse power. For the configuration scheme of the non-modulation single-bus satellite power system, the heavy power and high frequency instantaneous pulse of the satellite SAR load will directly cause the voltage pulsation of the non-modulation bus, resulting in the unstable input voltage of the platform bus converter. Base on the analysis of satellite load power demand under different mode and the load current value, evaluate the influence of satellite load of heavy power and high frequency pulse on platform bus converter. On the platform power converter input set filter unit, through the simulation analysis and verification of actual circuit, the filter unit can effectively control bus converter input voltage ripple within 2%, to ensure the reliability of the power supply system and power converter.
