Design and fabrication of closed loop Two Phase Interleaved Boost Converter with Type III controller
This paper presents design, fabrication and testing of a Two Phase Interleaved Boost Converter (IBC) with Type III controller by utilizing voltage mode control. The small signal modeling of IBC is derived in continuous conduction mode (CCM) of operation. A right half plane (RHP) zero is appeared in the control to output plant transfer function of the IBC. Due to non minimum phase problem, the Type III controller is designed by using `k' factor approach and is implemented for closed loop operation of IBC for achieving better dynamic performance and stability. The closed loop IBC with designed Type III controller is fabricated and tested in the laboratory. Simulation and experimental results have been produced to show the efficacy of the proposed converter control system.
