Abstract (en)
[origin: EP1071312A2] The method involves using a current pulse whose current amplitude (IMAX) is greater than the maximum permissible amplitude (IG) for continuous operation, whereby the arithmetic mean over a period is equal to the maximum permissible current intensity for continuous operation. An Independent claim is also included for a PWM drive arrangement.
