| Abstract: | 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. |
