Control of a New High Gain DC- DC Converter using ZN Method, PSO & BFA Optimization Techniques.

Lopamudra Mitra, Ullash Kumar Rout


A high voltage gain DC-DC converter is proposed which can be used with photovoltaic modules to get high output voltage. This converter can provides a high voltage gain and a PID controller is used to maintain the high output voltage of the proposed converter coupled with solar photovoltaic module. The PID controller is first designed using classical Ziegler Nichol’s method (ZN) and optimal control of the converter is obtained by using different optimisation methods like Particle Swarm Optimisation (PSO), Bacteria Foraging Algorithm (BFA) and its comparison is presented in this paper.
