Introducing the TGP Package

Micropelt thermogenerators offer a unique power

density, but mechanically they are quite sensitive. The

TGP packaged generator protects the TEG chip, facili-

tates system integration and automated assembly. Its

robustness simplifies thermal coupling and maximizes

power output.

2.1 TGP Properties

Different heat sink types of Sk422

2.2 Output Power Performance in Application

The matched output power depends on the character-

istics of the thermal path from heat source to ambient

(cold side). The heat sink type, dimensions and position

are of influence.

The TGP measurements are done with TE-CORE7 and

TE-CORE6, using different heat sinks from Fischer El-

ektronik, type Sk422 with a length of 33 mm, 50 mm

and 90 mm, placed in vertical position and thermal

compound (paste) between the hot source and the

thermal input.
