| Zusammenfassung | In this paper, a new device for power and rms value measurement is presented. Unlike the commercially available measurement equipment, this device is not limited to special waveforms. As a reaction to the increasing use of energy harvesters which gather energy from the ambience to power low power electronics, it is necessary to develop new measurement equipment that is not limited to sinusoidal signals as the harvesters will generally deliver nonsinusoidal signals. Therefore, a new device is presented which is based on a isothermal operating mode of a planar multijunction thermal converter (PMJTC). Differing from the former use of these PMJTCs, this one has been equipped with an additional gold heater and is operated by a regulating circuit which is electrically isolated from the input. The output signal of the regulator is recorded and analyzed to determine the power and rms value of the input signal. |
