Comparison of converter topologies and modulation schemes for high-speed motors

09. November 2015

The 2-level converter topology in combination with pulse width modulation (PWM) is the standard converter for rotational speeds up to several thousand revolutions per minute (rpm). When the application needs rotational speeds up to several hundred thousand rpm or has extreme motor efficiency requirements then other converter topologies and modulations schemes must be considered. Normally pulse amplitude modulation (PAM) is the optimal choice. What are the advantages and disadvantages of these two modulation schemes? Here is a guide to help in making the best selection.
