1. A powertrain system, comprising:
- a first prime mover;
a second prime mover;
a transformer module that includes a planetary gearset having a first rotary element connected to the first prime mover, a second rotary element connected to the second prime mover, and a third rotary element comprising an output member of the transformer module;
at least one gear meshed with the second rotary element, the second prime mover connected to the second rotary element through the gear;
a clutch for selectively inhibiting rotation of the second rotary element; and
a power shunt between the first prime mover and the second prime mover, wherein the power that is transmitted through the power shunt between the first prime mover to the second prime mover is not transmitted through planet gear teeth of the planetary gearset while transmitted through the shunt, and wherein the first rotary element is a ring gear of the planetary gearset.
