Abstract
In accordance with at least one aspect of this disclosure, a method for pulse width modulation control includes resolving a reference vector for any number of active space vectors to determine a voltage offset for the reference vector, adding the voltage offset to each active vector to determine a modified modulated signal to be added to a carrier signal, and controlling, with a control module, a switching circuit based at least in part on the modified carrier signal.
