摘要:For forming ##EQU1## in a pulse width multiplier, two input voltages b. sub.i aresummed at the input of an inverter and are added, after each passes through a separateswitch and proportional stage, at the input of a smoothing stage, to the inverter outputsignal. The switches are actuated by switching pulses which are width-modulated inaccordance with the factors c.sub.i. The calculated sum is present at the output of thesmoothing stage. Great accuracy in field-oriented control of rotating- field machines ispossible when vector analyzers and vector rotators designed in this manner are used.
