Electric vehicle with improved electric drive system

摘要

An apparatus includes at least one energy source 102 and a drive system 106 coupled to the at least one energy source 102. The drive system 106 converts electrical power received from the at least one energy source 102 and provides converted electrical power for driving at least one load 118. The drive system 106 includes a first converter 110, a second converter 112, and a first switch module 114 coupled to outputs of the first and second converters 110,112. When the apparatus is operating under a first mode, the first switch module 114 is switched to assume a first state to allow a first output electrical power provided from the first converter 110 and a second output electrical power provided from the second converter 112 to be combined for driving a first load with the combined output electrical power.
