Abstract:
 Abstract:The fundamental voltage of the inverter can be effectively improved with over-modulation. It
needs complex real-time calculation or look-up table for traditional SVPWM over-modulation algorithm,
which is not easy to implement. A over-modulation algorithm for SVPWM inverters is presented,which
was simple and suitable for digital implementation. The inverter transited from the linear operation to the
six-step operation smoothly. The harmonic components and the total harmonic distortion of the output volt-
age were analyzed. The over-modulation algorithm experiments were carried out on the two-level inverter
vector control system. Theoretical analysis and experimental results verify that the algorithm is convenient
and feasible,with low THD.
