Abstract: The matrix converter (MC) for motor drive applications and energy conversion systems is steadily
increasing due to its main advantage of performing a direct coupling between two three-phase alternating
current sources without the need of an intermediate direct current bus. The input filters characteristics design
for matrix converter system: to reduce the high harmonic components at the main power supply current and to
improve the input voltage distortion for matrix converter, the unity power factor at the main power supply side
is only achieved at the high output load and decreases greatly at the light load conditions. This paper proposes
a new direct space vector modulation (DSVM) method to achieve the required displacement angle between input
voltage and input current of matrix converter. A new switching strategy is introduced based on the maximum
compensated angle and for the controllable input power factor of matrix converter. The power factor
compensation algorithms using the new DSVM method to achieve the maximum IPF are presented, in which
compensation algorithm I is based on using the input filter and power supply parameters to estimate the optimal
compensated angle. Compensation algorithm II is subsequently proposed using a proportional–integral
controller to overcome drawbacks presented in compensation algorithm I. Simulation results with inductive
load (RL) are shown to validate the effectiveness of the proposed method.
Keywords - Direct space vector modulation (DSVM) method, input filter, matrixconverter (MC).
