What are DC-DC Converters?
DC-DC Converters transform an input direct voltage into another stable output for loads at a different level (e.g., 24→12 V or 48→12 V). There are isolated versions to separate grounds and avoid loops, and non-isolated versions with higher efficiency and compactness.
Advantages and limitations
- Protection of sensitive equipment against line variations.
- System optimization by using a single battery bank.
- Limitations: thermal dissipation and currents; respect the rated power.
Applications
- Caravans, boats, and electric vehicles.
- Auxiliaries in off-grid or hybrid PV systems.
How to choose
- Define input/output and whether you need galvanic isolation.
- Size for continuous and peak power and current.
- Integrate suitable fuses/circuit breakers and cable cross-section.
