DC-DC CONVERTER (i-ELOOP) [i-ELOOP]

id131704503000


Purpose, Function

•  To supply the power generated by the generator to the vehicle’s electrical devices, the DC-DC converter (i-ELOOP) performs control according to the engine operation conditions.
•  To prevent electrical circuit failure, part over-heating, or ignition due to large amounts of current, if the power supplied from the capacitor (i-ELOOP) exceeds the rated voltage of the vehicle’s electrical devices, power cannot be supplied directly to the vehicle’s electrical devices. As a result, the DC-DC converter (i-ELOOP) lowers the maximum 24.3 V voltage to 12 V, and then supplies power to the vehicle’s electrical devices.

Construction

•  The DC-DC converter (i-ELOOP) is located behind the battery.
