DC-DC Converter Applications
DC-DC converters are used in 220V/110V battery powered systems in order to obtain low voltages 24V or 48V. The converters take advantage of redundancy to ensure a highly reliable power supply to low-voltage loads. This eliminates separate use of 24V or 48V back-up batteries. 220V or 110V battery in combination with the DC-DC converter provides on uninterrupted supply to the low-voltage devices.
DC-DC converters can also be used to supply high voltage loads of 220V or 110V from a 24V or 48V battery supply, eliminating use of separate 220V or 110V batteries.
The main benefit of using DC-DC converters is a reduction in the number of battery based supply systems with different rated voltages, which saves the cost 0of installing and maintaining the multiply batteries. Back up time of all loads is the same.
