Power loss estimating in GaN E-HEMT based synchronous buck-boost converter

This paper investigates the state space averaging of a four-phase Interleaved Boost Converter (IBC) powered by fuel cells. The state space averaging technique is a method to model the converter as time independent which is defined by a set of differential equations which will be useful for designing the controllers [18]. In this paper, mathematical models developed using state space averaging technique are presented for the proposed IBC. The power loss calculations are also computed. Simulation of IBC with fuel cell as the source is carried out in MATLAB and the results are presented and discussed.

This paper deals with the design and simulation of two stage interleaved boost converter (IBC) for electric vehicle (EV) applications. The IBC is considered as a better solution among the different DC-DC topologies for EV for reducing the current ripple, power loss and the size of the components. Traditional DC-DC boost converter (BC) is not applicable for high power applications. Use of interleaving technique minimizes the voltage stress on the switching devices and to be improving the converter performance. Simulation is carried out using MATLAB/Simulink software. The prototype of two stage IBC is fabricated to test the performance. Hardware results shows that the inductor power loss is minimum at a switching frequency of 5 kHz compared to that of 10 kHz. The output power at the load end is maximum for 5 kHz switching when compared with 10 kHz switching. The study shows that the operation of IBC at 5 kHz improves the performance.
