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