The work presented in this paper proposes an approach
to reduce the common mode voltage at the output of matrix converters
when a direct torque control scheme is employed to drive a permanent
magnet synchronous motor. A mathematical analysis of the common
mode voltage at the output of matrix converters is ﬁrstly carried out
which is then corroborated by simulation results. Based on this ana-
lysis, a very simple algorithm to reduce the common mode voltage is
proposed and investigated. Finally, experimental results corroborating
the eﬀectiveness of the proposed method are shown.
