DC/DC Converters – When a system requires several different DC voltages
A DC/DC converter can be used when several DC voltages are required in one system. It is relatively common for the propulsion to have one system voltage while maneuvering and instrumentation require another. For example, a forklift with 48V or 80V for propulsion might have 24V for instrumentation. Smaller utility vehicles are powered by both 48V and 96V, while the instrumentation is supplied with 12V.
DC/DC converters are also used to separate the primary power supply from connected equipment, preventing the occurrence of unwanted currents. They can also be used to create an isolated and fully regulated voltage supply for connected equipment.
