摘要

本文的目标是设计和开发一种适用于空间应用的宽输入电压范围的、稳定的空间级OCXO和运载火箭电源。空间应用的标称输入电压为28V直流母线。电源的最终用途是供应各种OCXO。卫星使用提供单输出的电源单元(PSU)。该转换器采用正激转换器拓扑设计，采用离散LDO来满足要求的规格。电源采用电压模式设计，并采用前馈控制方法，以提供优越的CS101性能。该转换器在输入电压为24V-36V时，开关频率为150khz，输出功率为9W。

Space borne forward converter with discrete LDO to power OCXO

The object of paper is to design & development of consistent, robust space grade power supply for space application of OCXO & launch vehicle with wide input voltage range. The nominal input voltage of space application is 28V DC bus. The end use of power supply will be for supplying various OCXO. The Satellite is using power supply unit (PSU) which provides single output. This converter is designed with Forward Converter Topology & discrete LDO is used to meet the required specifications. The power supply has been designed by Voltage mode with the feed forward control method has been implemented to offer superior CS101 performance. This converter delivers the output of 9W for the input voltage of 24V-36V at a switching frequency of 150 kHz.
