Optimal control of a high gain DC- DC converter

<p class="IEEEAbtract">Different types of power conditioning systems are mostly used with renewable energy systems. As the output solar photovoltaic (PV) is low high voltage converters required. These can be for both standalone and grid tied A gain DC-DC converter proposed which modules to get voltage. This provide a proportional integral derivative (PID) controller maintain coupled module. The PID first designed using classical Ziegler Nichol’s method (ZN) optimal control obtained by different optimisation methods like particle swarm (PSO), bacteria foraging algorithm (BFA) its comparison presented in this paper.</p>
