基于直流支撑的起重机用变频器后备电源方案

Solution of the Backup Power Supply for Inverter in Crane Based on DC-BANK

本文主要针对变频器的特点,提出一种新型的后备电源系统解决方案。采用直流电源,直接为变频器母排供电。文中为起重机变频器的后备电源应用设计提供了参考性的建议。

This paper introduces the new type backup power supply solution that applies to feature of inverter. The DC-BUS of inverter is supported by DC-power supply in such system. The reference case for backup power supply used inverter in crane is to table a proposal.
