Abstract: A wide-band high-frequency signal power detecting element provided, on a substrate (21) having an insulating property, with at least one thin film resistor (22a) which generates heat upon absorbing the power of a signal to be measured, first and second grounding electrodes (27 and 28) respectively formed of thin film conductors, a first thin film connecting section (24) which electrically connects the first grounding electrode (27) to the resistor (22a), a second thin film connecting section (25) which electrically connects the second grounding electrode (28) to the thin film resistor (22a) and, at the same time, is formed so that the interval between the first and the second thin film connecting sections (24 and 25) may become narrower as going toward the resistor (22a), and an input electrode (26) which is arranged between the first and the second grounding electrodes (27 and 28) and electrically connected to the resistor (22a).

Abstract: The invention comprises a drive controller arranged to provide electrical power from a power supply (10) to a machine (8) or load, over a long AC power cable of the order of kilometers. The drive controller (4) is arranged with circuits and/or control processes to provide AC current at a constant ratio of voltage and frequency to said machine (8) or load. The drive controller maintains voltage and frequency at the machine terminals despite fluctuations in voltage and/or frequency that would ordinarily be caused by the load. This is done by estimating the voltage and current at the machine terminals and adapting the drive controller output accordingly to actively vary the converter output dependent on the load of the machine or other load. In other aspects of the invention a method and a computer program for carrying out the method are described.
