Two Phase Interleaved Boost Converter: Design, Modeling, Analysis and Control with GUI Applications
Keywords:Interleaved boost converter, photovoltaic, PID, Ziegler-Nichols tuning, GUI
The two level interleaved boost converter (IBC) is for low input voltage (battery or photovoltaic or Fuel Cell)
applications. The interleaved multi-channel converter is very popular these days because of its ability to reduce current
ripples. In high power applications, parallel operation of boost converters is recommended. These paralleled boost
converters can be operated in interleaved mode. Interleaved mode of operation improves the steady state and dynamic
performance of the system. In addition, low EMI and low stress in the switches are expected.
The IBC has been designed for low input voltage applications. The IBC has been modelled and analyzed using
state space averaging and small signal analysis technique. Graphic User Interface (GUI) applications have been
developed to save the timing of designing, modelling and analysis of IBC. Here the theory and application of designing
method of the PID controller for interleaved boost converter is discussed. GUI applications have been developed for
various tuning methods of PID controller for IBC.
