The design of high voltage gain DC-DC boost converter is carried out with the addition of the Voltage Multiplier (VM) method. Here the coupled inductor and VM methodologies are proposed to reduce the switching and conduction losses of the Metal Oxide Semiconductor Field Effect Transistor (MOSFET). The Zero Current Switching (ZCS) technique with coupled inductor leakage inductance is used to operate the MOSFET. The leakage inductance is used to decrease the reverse recovery current across the diode. The design procedure of the boost converter and corresponding output waveforms are presented in this paper. Photovoltaic (PV) source converter with coupling inductors soft switching technique has been analyzed and tested in this paper.

High Voltage Gain

High step-up DC-DC converters are necessary in photovoltaic energy generation, due the low voltage of the panels source. This article propose the Doubler Output Coupled Inductor converter. This converter is based in boost converter and utilize switched capacitors and a coupled inductor to maximize the static voltage gain. The converter achieve a high voltage gain with low turns ratio in the coupled inductor and an acceptable duty cycle. Can highlight the converter utilize low number of components and have low voltage and current stresses in semiconductors. To validate and evaluate the operation of the converter a 200W prototype is simulated.

AbstractHigh switching frequency and high voltage gain DC-DC boost converters are required for electric vehicles. In this paper, a new high step-up boost converter (HSBC) is designed for fuel cell electric vehicles (FCEV) applications. The designed converter provides the better high voltage gain compared to conventional boost converter and also reduces the input current ripples and voltage stress on power semiconductor switches. In addition to this, a neural network based maximum power point tracking (MPPT) controller is designed for the 1.26 kW proton exchange membrane fuel cell (PEMFC). Radial basis function network (RBFN) algorithm is used in the neural network controller to extract the maximum power from PEMFC at different temperature conditions. The performance analysis of the designed MPPT controller is analyzed and compared with a fuzzy logic controller (FLC) in MATLAB/Simulink environment.
