| Abstract |
This paper presents six methods improving the output current waveform of a PWM voltage source inverter.
Due to several delays and other effects during
a switch over process of a half bridge typical delay
errors can be seen which are not in context to the
modulation strategy. Considering drive systems designed
for low torque ripple or high speed it is definitely
not sufficient using an optimised modulating
strategy only. In contrast to the decreased load current
harmonics the delay errors are coming more and more into effect when the switching frequency is
increased. |
