A simple and effective space vector pulsewidthmodulation technique for six-phase voltage-source-inverter-fed split-phase induction motors is presented in this paper. The approach employs dual three-phase space vector modulators equipped with overmodulation schemes that compensate for the voltage gain reduction due to the use of two independently controlled(More)
This paper presents a method for designing linear controllers to achieve robust tracking and disturbance rejection properties. Wide range of references and disturbances such as step and sinusoid forms are covered. The proposed control structure comprises a combination of state-feedback and output-feedback strategies. The output-feedback structure is(More)
In this paper a 4 kV solid-state switch is proposed for telecommunication applications. This switch is constructed by series connection of MOSFETs. Rise and fall time are very important in repetitive pulse power devices. This switch has Rise time lower than 20 ns and fall time lower than 80 ns, which is tailored for telecommunication purposes. Using a(More)
