DC-DC converter for electric scooters

23 October 2013 Power Electronics / Power Management

Murata announced that it will shortly commence mass production of a dual-output, non-isolated DC-DC converter designed specifically for electric scooter applications.

The 200 Watt MPD7K046 converter accepts an input voltage in the range of +36 to +60 V d.c. around a nominal +48 V d.c. The primary output provides +12 V d.c. at a continuous rating of 10 A, and up to 18 A peak current. The secondary output delivers a +5 V d.c./1 A supply that suits logic rails and as a USB supply. Energy efficiency is typically 95%.

This converter has already achieved a design win in Terra Motors’ new A4000i electric scooter, where it will enable power from the scooter’s battery to be used for auxiliary equipment such as headlights by stepping it down from +48 to +12 V d.c.
