A low voltage ride-through solution for an indirect three-level matrix converter based open-end winding drive is demonstrated. The proposed method uses the input filter capacitors to exchange the inertial energy from the motor and thereby maintain the flux in the motor during grid fault conditions. The input filter capacitors act as the voltage source for inverters during the fault. Ride-through is...
Multi-level matrix converter (MMC) is a three phase ac-ac converter that can synthesize three or more levels at the output voltage while maintaining desired input power factor. In this paper a new converter, Capacitor clamped Multi-level Matrix converter (CMMC) has been proposed as an addition to the MMC family. In comparison to conventional matrix converter, the CMMC offers an additional level at...
An indirect capacitor clamped multi-level matrix converter has been proposed in this paper. In comparison to the conventional matrix converter the proposed converter makes available half line voltages in addition to the line voltages at the converter output. This increased level comes at the cost of additional bi-directional switches and clamp capacitor. Indirect space vector modulation scheme, for...
A novel hybrid indirect multi level matrix converter has been proposed in this paper. In comparison to the conventional matrix converter the proposed converter makes available the input phase voltages and half phase voltages in addition to the line voltages at the converter output. This increased level comes at the cost of additional bi-directional switches and clamp capacitor. Indirect space vector...
A new direct multi level matrix converter has been proposed in this paper. In comparison to the conventional matrix converter the proposed converter makes available the input phase voltages in addition to the line voltages at the converter output. This increased level comes at the cost of three additional bi-directional switches connecting output terminals to the filter capacitor neutral. Direct space...
A conventional matrix converter (CMC) is a direct ac-ac converter without the need for a DC bus. This paper proposes a direct three level matrix converter (DTMC) topology which is advancement to the CMC in terms of considerable reduction in THD and lower switching stresses. As opposed to CMC which allows the output line voltage to be either input line voltage or zero, the DTMC provides an extra level...
