Abstract:The two stage matrix converter (TSMC) is used in the starter/generator system to improve the reliability of the system.The id=0 space vector control strategy is used at starting,and the unidirectional switch side of the TSMC is worked in the no controlled rectifier state.To solve the commutation problem caused by over 30° motor’s power factor angle,the current circulating paths with different switch states in a sector are analyzed.Then a feasible safe commutation modulation strategy is proposed,which selects appropriate vectors and allocates times reasonably,and thus ensures the existence of the current circulation loop in the system.In addition,the system uses the current closed-loop control to realize constant torque starting.The feasibility and effectiveness of the start strategy for safe commutation is validated by simulation and experimental results.
