| Abstract |
This paper presents the simulation results of two vector modulated 5 kVA matrix converter topologies:
a conventional direct matrix converter (DMC) and an indirect matrix converter (IMC). The vector
modulation method used with both topologies was indirect vector modulation (IVM), which is
presented using space vector theory instead of conventional matrix form.
Functionally the IMC is very similar to the DMC but it has separate line and load bridges instead: i.e.
it has dc-link without passive components. Both topologies produce sinusoidal input currents and
nearly identical output voltages when they are modulated using the IVM.
Most research on IMC modulation has been done using triangular wave voltage command modulation.
Thus no comparison of these topologies was possible regardless of the modulation method used. When
both topologies are modulated with the IVM the effects of the modulation method do not produce
differences. Thus the differences observed are caused by the topologies. The benefits of both the IMC
and the DMC are sinusoidal input and output current waveforms, low input current distortion and
controllable input power factor. Simulations confirmed these benefits. |
