“…Es müssen deshalb regelungs technische Anpassungen vorgenommen werden, um erstens den Verstärkungsabfall so weit wie möglich zu kompensieren und zweitens die Auswirkung der Öffnung des Regelkreises durch das Sättigungsverhalten des Stellglieds zu vermeiden; eine Diskussion dieser Aspekte erfolgt in [407].

Operating voltage pulse width modulated (PWM) inverters in the overmodulationi region extends their voltage and power range and improves their dynamic performance. This payer is a contribution to the extension of the operating range of the classification algorithm for the implementation of the Space Vector Modulation (SVM) in the pulse dropping region. ' b o different schemes are proposed to continuously increase the output voltage up to the maximum attainable value in a controllable manner. Mathematical analysis and experimental results verify the validity of the proposed schemes.

The equivalence of triangle-comparison-based pulse width modulation (TCPWM) and space vector based PWM (SVPWM) during linear modulation is well-known. This paper analyses triangle-comparison based PWM techniques (TCPWM) such as sine-triangle PWM (SPWM) and common-mode voltage injection PWM during overmodulation from a space vector point of view. The average voltage vector produced by TCPWM during overmodulation is studied in the stationary (a-b) reference frame. This is compared and contrasted with the average voltage vector corresponding to the well-known standard two-zone algorithm for space vector modulated inverters. It is shown that the two-zone overmodulation algorithm itself can be derived from the variation of average voltage vector with TCPWM. The average voltage vector is further studied in a synchronously revolving (d-q) reference frame. The RMS value of low-order voltage ripple can be estimated, and can be used to compare harmonic distortion due to different PWM methods during overmodulation. The measured values of the total harmonic distortion (THD) in the line currents are presented at various fundamental frequencies. The relative values of measured current THD pertaining to different PWM methods tally with those of analytically evaluated RMS voltage ripple.
