ELECTRIC VEHICLE WITH IMPROVED ELECTRIC DRIVE SYSTEM
First Claim
1. An apparatus, comprising:
- at least one energy source; and
a drive system coupled to the at least one energy source, the drive system configured to convert electrical power received from the at least one energy source and provide converted electrical power for driving at least one load, the drive system comprising;
a first converter;
a second converter; and
a first switch module coupled to an output of the first converter and an output of the second converter,wherein 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.

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.

13. A vehicle, comprising:
-
a first direct current (DC) to alternative current (AC) converter; a second DC-to-AC converter; a controller coupled to the first DC-to-AC converter and the second DC-to-AC converter, the controller configured to send respective control signals to the first and second DC-to-AC converters to enable the first and second DC-to-AC converters to perform power conversion; a first electric motor coupled to the first DC-to-AC converter; and a second electric motor coupled to the second DC-to-AC converter, wherein when the vehicle is operating under a first mode, the first electric motor is powered by both the first and second DC-to-AC converters, and the second electric motor is not operating; and wherein when the vehicle is operating under a second mode, the first electric motor and the second electric motor are separately powered by the first and second DC-to-AC converters. - View Dependent Claims (14, 15, 16)
