“…(1)(2)(3)(4) Therefore, a step-up DC converter would be required to boost the 48 V DC power up to at least 156 or 312 V. Compared with the conventional boost converter, the coupled-inductor boost converter could more easily provide a high-voltage step-up ratio. (5)(6)(7)(8)(9)(10) However, the resulting current ripple in the low-voltage side would become higher than that in conventional topology, which would also result in additional power losses.…”

A high-voltage step-up ratio inverter for applications using batteries as the input power source is proposed to supply the emergency power requirement from a battery pack when the grid is down. The proposed inverter is composed of an interleaved coupled-inductor boost converter and a three-leg full-bridge inverter. Four series-connected lead acid batteries are used as the input power source. When 110 and 220 V AC outputs are required by the load sides at the same time, the 48 V DC input from the batteries would be boosted up to 350 V DC for the three-leg inverter to provide AC output power. However, if only 110 V AC is required, the proposed control strategy would reduce the step-up ratio for a lower DC link voltage of 175 V DC to enhance the conversion efficiency. Moreover, to minimize damage to the batteries, the interleaved circuit topology is adopted to reduce the input current ripple. A prototype with 400 W rated output power is finally constructed. The controller is implemented with a low-cost microcontroller, HT66F50. From the experimental results, it is seen that even under unbalanced load conditions, the output AC voltage is well controlled. The total efficiency of the proposed inverter with 110/220 V AC output is 89.8%, and the efficiency of the inverter with only 110 V AC output is 91.1%.

“…An interleaved PFC that can meet the above two tasks will be investigated in this paper for its high power capacity, low switching losses, and reliable operation [2,3]. Although it can efficiently reduce power-frequency harmonic components, its fast switching circuit produces some high-frequency noises which pose a potential pollution to power grid and influence other operating devices connected to the grid.…”

Abstract:A power factor correction (PFC) converter with interleaved multi-channel topology is gaining increasing attention due to its ability in reducing input and output current ripples, but an Electromagnetic Interference (EMI) noise filter is still required for suppressing the large high-frequency switching noise that could potentially degrade the input power quality of the supplying grid and cause malfunctions to other grid-connected systems. In this paper, a magnetic modeling of an interleaved PFC converter with an input differential mode (DM) EMI filter has been successfully implemented, which considers the nonlinear behavior of the inductive component in the EMI filter. The Jiles-Atherton (J-A) model is applied to describe the filtering inductor whose core displays saturation and hysteresis. The simulation results are verified with the experimental test.

“…A current topic is the development of hybrid systems [25][26][27][28][29][30][31][32]; therefore, the addition of peripheral elements, such as auxiliary power units or backup sources intensifies the challenge of modeling highly coupled multi-physical systems. There are also complete studies concerning the design, improvement or modeling of converters for fuel cell applications (e.g., [33][34][35]). Kim, 2015 [36] proposed a process for implementing new renewable energy systems, and offered an analysis of the key factors affecting system performances of fuel cell systems.…”

Control of the Air Supply Subsystem in a PEMFC with Balance of Plant Simulation

This paper deals with the design of a control scheme for improving the air supply subsystem of a Proton Exchange Membrane Fuel Cell (PEMFC) with maximum power of 65 kW. The control scheme is evaluated in a plant simulator which incorporates the balance of plant (BOP) components and is built in the aspenONE R platform. The aspenONE R libraries and tools allows introducing the compressor map and sizing the heat exchangers used to conduct the reactants temperature to the operating value. The PEMFC model and an adaptive controller were programmed to create customized libraries used in the simulator. The structure of the plant control is as follows: the stoichiometric oxygen excess ratio is regulated by manipulating the compressor power, the equilibrium of the anode-cathode pressures is achieved by tracking the anode pressure with hydrogen flow manipulation; the oxygen and hydrogen temperatures are regulated in the heat exchangers, and the gas humidity control is obtained with a simplified model of the humidifier. The control scheme performance is evaluated for load changes, perturbations and parametric variations, introducing a growing current profile covering a large span of power, and a current profile derived from a standard driving speed cycle. The impact of the control scheme is advantageous, since the control objectives are accomplished and the PEMFC tolerates reasonably membrane damage that can produce active surface reduction. The simulation analysis aids to identify the safe Voltage-Current region, where the compressor works with mechanical stability.
