摘要： A method is for the pulse width modified control of switching elements in a frequency converter having N phases, in which for each phase the control pulses of the switching elements are derived from, in each case, one P-periodic control voltage. The P-periodic control voltages correspond to a superposition of sinusoidal control voltages of period P, that are shifted by 360/N degrees with respect to one another, by an N*P-periodic offset voltage that applies to all phases. The offset voltage is selected such that, at any time, exactly one of the P-periodic control voltages lies effectively on a modulating limit for the derivation of the switching pulses. Using this method, the excitation of resonances at the star point of a connected load may be clearly reduced.

摘要： A circuit arrangement allows a converter to be operated with supply voltages oscillating within broad limits. The intermediate circuit voltage of the converter is controlled to avoid unacceptably high currents, so that the intermediate circuit voltage is always higher than the peak value of the rectified supply voltage. For at least this purpose, the peak value of the rectified supply voltage is determined and compared to that of the intermediate circuit voltage. If the intermediate circuit voltage is less than the peak value of the rectified supply voltage, the intermediate circuit voltage is increased to exceed the originally set setpoint value. This prevents free-wheeling diodes from becoming conductive at undesirable times and causing excessive currents.

摘要： A method for extracting bitumen and/or extra-heavy oil from an underground deposit is provided. The energy for producing the steam and for the electric heating is generated in situ, for which purpose part of the extracted bitumen and/or extra-heavy oil is burned in an industrial turbine with a downstream generator coupled to the turbine. The industrial turbine may be a gas turbine or a steam turbine. In particular the industrial turbine with downstream generator is assigned a waste heat recovery steam generator which serves for generating the steam and accordingly takes the form of a boiler. Through intermediate storage of the bitumen and/or ultra-heavy oil produced it is possible to implement a self-contained closed circuit which operates autonomously, independently of any external energy supply, using approx. 20% of the extracted bitumen and/or extra-heavy oil for the purposes of extraction.

摘要： In a protective circuit for a converter having a plurality of phases, for each phase current of the phases, a signal proportional to the respective phase current is applied to a transformer circuit that, below and in the area of a limiting frequency, functions as a low-pass filter with the limiting frequency, and above the limiting frequency, functions as a divider. The outputs of the transformer circuit are applied to a maximum generator for forming the absolute value maximum. This maximum is fed to a comparator in which the maximum is compared to a reference value.
