| Abstract |
This paper presents a new modulation strategy
for matrix converters, which provides the maximum control
range including reactive input power. The modulation strategy
is based on modern representations of the switch state in the
space vector domain. There geometrical considerations lead to
a comprehensible strategy to determine free variables without
reducing the intrinsic control range of the switch matrix.
A comparison with other modulation strategies shows, that
this control range exceeds the control range of all previously
proposed modulation strategies. A further advantage is, that low
switching losses are expected, because a maximum of switches
are idle during a modulation period. |
