Abstract: An indirect matrix converter includes a rectifier module, an inverter module, and a control unit. The rectifier module includes three parallel-connected T-type bridge arms, and each T-type bridge arm includes a bidirectional switch and a power bridge arm. The power bridge arm includes a first switch and a second switch connected to the first switch in series. One end of the bidirectional switch is coupled to a first AC power source, and the other end thereof is coupled to a common contact between the first switch and the second switch. The control unit outputs a plurality of control signals to control the rectifier module and the inverter module, so that the first AC power source is converted into a second AC power source, or the second AC power source is converted into the first AC power source.
