This paper deals with a new PWM control scheme of matrix converters, which have been proposed by the authors. The PWM control scheme is characterized by the calculation algorithm using pseudo inverse and the performance that the output voltage can be controlled completely even if the input voltage is distorted. An experimental system, which consists of a matrix converter main circuit and a control circuit using a DSP and an FPGA, has constructed and tested. An PWM generator and a commutation sequencer are developed and implemented in the FPGA. Some experimental results show validity and usefulness of the proposed PWM control scheme. In addition, a new PWM control scheme for improvement of the output voltage utilization is also evaluated experimentally and tested.
