Abstract: A regenerative braking system of an automobile is disclosed. The system also includes an alternator, a plurality of supercapacitors and a power converter subsystem. The system also includes an automobile status sensing subsystem, which identifies a real time motion status of the automobile via one of an accelerometer and a pulse signal measurement. The power converter subsystem is operatively coupled to electrical system and the plurality of supercapacitors. The power converter subsystem transfers generated energy from the alternator and store the generated energy in the plurality of supercapacitors in an event of the braking of the automobile. The stored energy, which is stored in the supercapacitors, is slowly returned to the electrical systems of the automobile during idling, accelerating or running conditions.

Abstract: A method of estimating a temperature at a component of a device is provided. The temperature may be used to provide thermal load management of the device. In an exemplary embodiment, a switched mode power converter includes a power converter module and a switch that controls a switching cycle of the power converter module. A signal includes a bus voltage component and an oscillating signal component at least partially caused by switching of the switch. A switch instant of the switch can be isolated. A characteristic of the oscillating signal component of the signal can be detected. For example, a first peak voltage of the oscillating signal component can be detected after the switch instant. The temperature of the power converter module is estimated using the detected characteristic of the oscillating signal component. For example, the temperature can be estimated using the first peak voltage and best-fit curve parameters in solving a linear or a quadratic equation.
