摘　　要：为了获得可应用于航天器系统的稳定的供电电源,采用高性能升压-降压开关稳压控制器LTC3780,设计在低压、高压和正常供电时都能实现预期输出电压的电源转换电路;利用LTspice软件对该电源转换电路进行工作性能仿真,主要对不同输入电压时的输出电压和不同负载时的带载能力进行了仿真,通过仿真实现了稳定的电压输出和较强的带载能力。In order to obtain a stable power supply which can be applied to the spacecraft system,a high performance buck-boost switching regulator controller LTC3780 was used to design a power conversion system which can achieve the desired output voltage whatever input voltage was lower or higher than the typical value.Its performance including output voltage and load capacity were simulated under different input voltages and different loads by LTspice.The simulation results demonstrated that this system had stable voltage output capability and large load capacity.
