DC to DC converter 100 includes first and second capacitors 102 and 104, an inductor 106 and first and second switching devices 108, 110. This may, in comparison with conventional converter arrangements, provide a higher output terminal voltage rating while capacitors are used at lower voltage ratings and/or reduce over-voltage occurrences due to susceptibility to capacitor parameter variation. The DC to DC converter may be bidirectional. An electric motor drive system (see figs. 4 and 5) comprises an energy storage device (402), a drive unit (404), an electric motor (406) in electronic communication wit the drive unit and a DC to DC converter (400, 500) as described above. |
