摘要
针对双轴太阳帆板驱动装置2个电机的控制要求,提出一种新型双轴帆板驱动线路盒(BSADE,biaxial solar array drive electronics)设计.该线路盒基于现有帆板驱动线路设计,通过在电机驱动线路中设计一种电流方向转换延时线路,解决了电流方向转换瞬间功率管容易对穿的问题,确保了驱动线路工作的安全性,使得原先大功率管才能实现的线路选用小功率管实现,达到了小型化目标.通过对电机驱动线路和负载绕组进行交叉重组设计,解决了主备份线路间磁耦合问题,实现了严格冷备份目标,大大提高了可靠性.
A design of new biaxial solar array drive electronics is proposed according to the requirements for two-motor biaxial solar array. Based on the existing solar array drive electronics, via designing a current direction switching delay circuit, the problem that power transistor is easily short at the moment of current direction switching is solved and the safety of the circuit is ensured. The small power transistor can be used to simplify the design and realize the miniaturization. By crossing recombination between the array driving circuit and motor coil, the real isolation between the main and secondary electronics is en- sured and the reliability is greatly improved.
