摘要

本文研究了在电网电压长期下降的情况下不间断供电的实现方法，以保证望远镜旋转支撑装置在不降低其动力的情况下工作。这使得在部分电网供电的情况下，望远镜系统可以提供完整的工作范围。建立了由整流器、滤波器、三相双有源电桥和变频器组成的永磁同步电机驱动的三相双有源电桥功率变换器的数学模型，并考虑了方位轴轨迹测量望远镜的电驱动参数。

Three Phase Dual Active Bridge Power Converter Implementation in Power Supply System of Telescope Rotary Support Device

The article considers the method of uninterruptible power supply realization for the case of longterm grid voltage dips to provide work of the telescope rotating support device without reduction of its dynamics. That allows to provide full operation range for the telescope system in condition of partial power supply from grid. Mathematical model of three phase dual active bridge-based power converter is presented which consist of rectifier, power filter, three phases dual active bridge and inverter with permanent magnet synchronous machine drive and takes into account parameters of the electric drive of the azimuth axis trajectory measurements telescope.
