NOVELTY - The power module (1) has a power device that switches electric power. A thermoelectric device produces a harvested electric power. A plate dissipates heat produced by the power device. The thermoelectric device is provided in a primary thermal path between the power device and the plate such that a temperature differential across the thermoelectric device is formed between a respective top and bottom portions of the thermoelectric device. The harvested electric power is produced by the thermoelectric device based on the temperature differential.    USE - Power module of power electronics system of hybrid electric vehicle. Can also be used in semiconductor device of power electronics system of land vehicles such as automobiles.    ADVANTAGE - The thermoelectric devices have been arranged in between an exhaust pipe and a heat sink in order to produce electricity. The temperature differential is formed across the thermoelectric device when the power device is in operation. This temperature differential in the thermoelectric device causes the thermoelectric device to produce a voltage potential due to the See beck effect. This voltage potential is present at the thermoelectric device terminal. When this voltage potential is attached to a load, then electric power is produced as a result of the temperature differential across the thermoelectric device. The harvested electric power is produced by the thermoelectric device placed in thermal series between the power device and the base plate. This harvested electric power is produced from the waste heat produced by the power device, thus the thermodynamic efficiency of the power module in increased by thermoelectric device. Hence the less fuel is consumed by the vehicle provided with environmental and economical benefits.
