Abstract
An electronic device includes at least one electronic component, a gradient heat-flux sensor GHFS based on thermoelectric anisotropy and conducting heat generated by the electronic component, and a controller adapted to manage electrical current of the electronic component at least partly on the basis of an electrical control signal generated by the gradient heat-flux sensor and proportional to a heat-flux through the gradient heat-flux sensor. Therefore, the electrical current and thereby also the heat generation of the electronic component are managed directly on the basis of the heat-flux generated by the electronic component. Thus, the electrical current can be managed without a need for voltage and current measurements which may be challenging to be carried out with a sufficient bandwidth especially when the switching frequency of the electronic component is on a range from hundreds of kHz to few MHz.
