Abstract
The voltage regulating device, compensating the error due to the heat dissipated by the power element that drives the load, specifically an excitation winding of a motor car battery charging alternator, comprises a control stage including a temperature sensing element and a power stage driven by the control stage for generating an output voltage dependent on the ambient temperature. The power stage includes a sensor for detecting the power dissipated therein and generating a dissipated power signal fed to a compensation section in the control stage which also receives the temperature signal detected by the temperature sensing element for generating an actual ambient temperature signal unaffected by the error due to internal heat dissipation.
