Study of multi-pulse PWM for multi-level BTB for distributed generation system

This paper describes about the multi-level BTB converter system installed in the power distribution system with the dispersed generation, such as solar power, wind power, or others. This type of generation is often installed at the end of the power distribution system. This makes the current flow in the power distribution system unexpected profile and sometimes cause too much high voltage. To avoid such phenomenon, installation of a power flow controller is one of the solutions. However smallness, lightness and low cost is indispensable. We propose to use the multi-level BTB converter system with the new PWM control as the power flow controller or STATCOM.
