基于超级电容的动态测试系统电源设计

动态信号具有突发性和瞬态性的特征,针对测试中系统遭受振动、冲击等原因造成电源抖动或意外掉电而导致测试失败的问题,设计并制作了基于锂电池和超级电容混合储能的电源。大容量的电池作为测试系统的常用电源,而高密度的超级电容作为备份电源以满足恶劣环境下瞬态信号的测试需求。实验结果表明,混合储能的方式能应对冲击造成的电源抖动和断电问题,提高动态测试的可靠性。

Design of Dynamic Testing System Power Based on Super Capacitor

Dynamic signal has sudden and transient nature, vibration, shock may cause accidental power-down,leading to test failures. As for this problem,this paper designed and produced power storing energy based on the lithium battery and super capacitor. To meet the needs of harsh environment testing of transient signals, large capacity battery plays the role of a common power supply for test systems, and high-density super capacitor plays the role of a backup power supply. Experiment results show that the hybrid energy storage mode can solve power jitter and power down caused by the impact, improving the reliability of the dynamic tests.
