Abstract
The present invention is directed to transmission systems, components, and assemblies including a thermoelectric assembly. The thermo-electric assembly may include a chamber and a thermo-electric device in thermal communication with the chamber, wherein the thermo-electric device forms part of a static H-bridge configuration. The assembly may also include a first temperature sensor in thermal communication with the chamber and a second temperature sensor in thermal communication with an ambient environment. A variable power supply having a power output connected to the thermo-electric device and having a control input is included, in addition to a linear driver having an output connected to the thermo-electric device. The assembly has a controller responsive to the first and second temperature sensors that controls the thermo-electric device, wherein the controller connects to the control input of the variable power supply, wherein the controller drives the thermo-electric device with the linear driver when a temperature of the chamber is within a predetermined temperature range of a temperature set point for the chamber, and wherein the controller drives the thermo-electric device…
