Abstract
An apparatus and a method for determining a power value of a target in the form of an AC circuit () having an AC power source (). The method involves operating () a controllable DC power source () to provide DC power to a DC circuit () and measuring () at least one thermal parameter related to power dissipation of the DC circuit () and of the target AC circuit (), wherein at least one heat sink () is thermally coupled between the DC circuit () and the target AC circuit (). The method further involves controlling () the DC power source () based on the measured at least one thermal parameter to reduce a difference in power dissipation between the DC circuit () and the target AC circuit (). The method then involves, when thermal equilibrium is reached (), determining the power value () of the target AC circuit () by retrieving () at least one real-time measurement of at least one electric parameter of the DC circuit (), calculating () a DC power value of the DC circuit () based on the retrieved at least one real-time measurement of the at least one electric parameter, and calculating () the power value () of the target AC circuit () using the calculated DC power value.
