1. DC-DC converter selection:
Power matching: The converter's rated power should exceed the system's maximum load power.2. Control strategy:
MPPT (Maximum Power Point Tracking): For photovoltaic or wind power systems, MPPT algorithms maximize the utilization of renewable energy.
Load balancing: When multiple batteries are connected in parallel, load balancing algorithms ensure even load sharing among batteries.3. Thermal design:
Heat sink selection: Choose a suitable heat sink based on the converter's power and operating environment.4. EMC design:
Filtering: Add input and output filters to reduce electromagnetic interference.5. DC-DC Converter Topologies
Common DC-DC converter topologies include:Summary
DC-DC converters play a vital role in energy storage systems. Through proper selection, design, and control, efficient, stable, and safe power management can be achieved. In practical applications, various factors should be considered based on specific system requirements and operating environments to choose the appropriate DC-DC converter solution.
