Interleaved High Step up Dc-Dc Converter with PID Controller

Rakesh Kumar Goudanaikar, K. Shanmukha Sundar

Multiphase dc-dc converters are widely used in modern power electronics applications due to their advantages over single-phase converters. Such advantages include reduced current stress in both the switching devices and passive elements, reduced output current ripple, increase in output voltage and overall efficiency and so on. The output current ripple of a converter can be significantly reduced by virtue of the interleaving connection. This paper presents a design and simulation of an interleaved high step up DC-DC converter with PID controller. The control strategy of the converter is based on a Proportional-Integral-Derivative (PID) controller. The proposed converter achieves a high step-up voltage-conversion ratio without extreme duty ratio and the numerous turns-ratios of a coupled inductor and reduction in the input current ripple with the efficiency higher than 97%.The PID controller is used in the feedback to reduce the rise time and steady state error. The proposed interleaved high step up DC-DC converter model along with PID controller is modeled using SIMULINK and the simulation results are presented in this paper to authenticate the proposed scheme.
