Summary:This paper has presented the control strategy of Space Vector Pulse Width Modulation in over-modulation range by contrast. Based on the three-level inverter vector control theory, the cause of over-modulation generated is explained. Several typical over-modulation control strategies are summarized in detail, such as typical dual-mode strategy, typical single-mode strategy, the minimum phase angle error strategy and the minimum amplitude error strategy. Over-modulation algorithm can improve effectively output fundamental voltage, shorten the motor dynamic response time, and expand steady-state operating region. But some problems included harmonic current issue and DC bus voltage instability are pointed out. To deal with these problems, the improved over-modulation algorithms have an effective influence on accurate control of system.
