In recent years, electrification of powertrain has become mainstream to meet regulatory fuel economy and emissions. The present invention of dual mode power-split transmission relates generally to hybrid electric drive systems and its configuration. The designed transmission is capable of operating in two modes, input split and compound split mode thereby providing three mechanical points and an ability to maintain high transmission efficiency and continuous power output throughout the speed range. This is due to specific arrangement of power sources, clutches and designed gear ratios of the planetary gears. The dual mode power-split transmission also makes it possible to downsize the electric machines.
