Abstract: The invention relates to a method for determining a rotational angle output signal of a position sensor. In this method, a rotational angle position is measured as a measured angle signal (?Mess) as a function of time (S100), and the measured angle signal (?Meas) is corrected using a correction angle signal (?Corr) (S110) in order to obtain a filter input angle signal (?FiltInp). The correction input angle signal (?CorrInp) is output as the rotational angle output signal (S140). Furthermore, the filter input angle signal (?FiltInp) is filtered (S120) in order to obtain a correction input angle signal (?CorrInp), and the correction angle signal (Corr) is determined as a function of the correction input angle signal (?CorrInp), a frequency (fMeas) of the filter input angle signal (?FiltInp) and an angle error signal (?Error) (S130), wherein the angle error signal (?Error) is determined by calculating a difference between the filter input angle signal (?FiltInp) and the correction input angle signal (?CorrInp).

Abstract: A power supply system controls the source impedance of a generator in real time utilizing two amplifiers having asymmetrical power profiles in reference to a nominal load impedance that are diametrically opposite in reference to the nominal load impedance. Variations in power profiles may be achieved by using different topologies for each of the amplifiers or implementing a phase delay network. The output power from the first and second amplifiers may be combined using a combiner circuit or device and the output power from the combiner is transmitted to a plasma load. The output power of each amplifier may be independently controlled to alter one or more characteristics of the output power signal provided by the individual amplifiers. By changing the ratio of the output power of the first amplifier to the output power of the second amplified, the source impedance of the generators may be varied in real time.
