ENFORCED ZERO VOLTAGE LOOP

摘要

A method (148) of controlling a motor (110) is provided. The method may determine one of a switching period, a fundamental cycle, and a current target threshold per phase leg (142) of the motor (110) having at least one high voltage transition point (144); determine a dwell period (146) to be enforced at the transition point (144) between an engagement of a first switch (132-1) of the phase leg (142) and an engagement of a second switch (132-2) of the phase leg (142) where each of the first switch (132-1) and the second switch (132-2) being selectively engageable between a first state and a second state; engage the first switch (132-1) from the first state to the second state at the transition point (144); and engage the second switch (132-2) from the first state to the second state after the transition point (144) and upon expiration of the dwell period (146).
