The matrix converter (MC) has attracted considerable attention due to its several good features. However,the MC needs a lot of power switches, which leads to the complex topology and control,so the development of the MC has been limited to some extent. In this paper, the 'indirect SVPWM' modulation method based on the 'fictitious dc link' is researched and verified by simulation and experiment. The experiment is implemented with DSP and CPLD to complete the four-step commutation strategy. The resultant output voltages and input currents are sinusoidal and good effect is achieved.
