Abstract:

Aiming at the low voltage transmission of Ultra Spare Matrix Converter (USMC), a new topology of USMC with Boost boost circuit is proposed. The Boost circuit is added in the DC link of USMC to increase the output voltage of DC link, so that the inverter stage can output a higher voltage. Thereby, the voltage transmission ratio range is widen. In addition, combined with the SVPWM modulation strategy, the voltage transmission ratio and output power factor range of the new USMC topology are derived. It lays a theoretical foundation for the application of USMC. Finally, the Matlab/Simulink simulation is included to verify the correctness and feasibility of the topology.

Key words:uultra spare matrix converter(USMC); the Boost circuit;space vector modulation;vvoltage transmission ratio
