Closed Loop Control of DC to DC Converter with Hybrid Input Sources
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 1
Abstract
This paper proposes a closed loop based dc-to-dc power conversion circuit for distributed generation systems. With the two-port converter, the load can be powered from two different dc sources, which can be a combination of two from a solar-cell panel, a fuel-cell set, a battery bank, etc. and for continuous supply and reliable output we extended the circuit into closed loop system. The power conversion circuit consists of two active power switches by commonly using an inductor and an output filter capacitor. By adjusting the duty-ratio of the active power switch and gate triggering pulses of the inverter with the closed loop method, the voltage regulation at the output as well as the power coordination between two input sources can be made. The circuit operation is described in detail with the theoretical analysis and computer simulation. An experimental circuit has been built and tested to verify the analyzed and simulated results.
