Multiple current source inverter using tap conversion

In multiple current source inverter, generally, transformer connection method and direct connection method in output side have been used. But these methods have faults such as the increment of the number of inverter and the need of the transformer for changing phase in order to get above 12 phase. In this system, we obtained the output currents of 24 phase by adding 2taps in 12 phase inverter. Therefore, this system has such characteristics as the miniaturization of devices and the simplicity of control signal by controlling two inverters and two SCRs for changing taps.
