Through the use of a passive resonant soft-commutation cell, which besides providing improvements in efficiency and reduced electromagnetic interference, produces a naturally controlled supercapacitor charger circuit. Supercapacitors are employed in order to provide a proper startup of the PEMFC and to improve its dynamic response. The control strategy is implemented using a digital signal processor and is based on the average current control method for sinusoidal input current imposition ensuring, therefore, a high input power factor and low harmonic distortion of current. The main features of the proposed solution are the use of a PEMFC as an energy storage system, which replace the battery banks commonly used in UPS systems, eliminating the common drawbacks related to working life and maintenance issues, and the use of a front-end converter with integrated PFC and dc–dc functions eliminating the necessity of using an additional and dedicated dc–dc converter for the PEMFC. During power failure or even in conditions of severe voltage sags on the ac mains, the PEMFC is activated assuring the continuous power supply to the electronic load connected to the dc link. In this paper, the authors present the full study description including experimental results that corroborate with the theory herein presented.

In this context, it has become inadmissible the occurrence of interruptions in power supply regarding various fields of work and services, among which one can cite telecommunications systems, devices employed in hospital emergency rooms, and flight control systems. In this sense, many companies invest in research studies, which focus on the development of solutions that avoid energy supply interruptions to their systems. The devices manufactured for this purpose were denominated as uninterruptible power supply (UPS), which commonly present a high power factor (HPF) front- end converter followed by a dc–ac or dc–dc stage (depending on the application) and uses rechargeable batteries such as sealed lead-acid or nickel cadmium, which use toxic heavy metals such as cadmium, mercury, and lead. In addition, the unpredictable working life along with limited charge–discharge cycles increase the cost concerning maintenance and replacement. On the other hand, fuel cells (FCs) are emerging as a reliable power source, since it is inherently clean and presents very high overall efficiency (40–60%). Unlike batteries, performance characteristics of the FCs such as great tolerance to high temperatures (from –40 °C to +50 °C), lower maintenance requirements, scalability, and higher power density, make them a very attractive alternative to UPS systems. Due to the fact that FCs do not have the capacity to respond immediately to fast load changes or to startup as soon as it is required, supercapacitors can be used in conjunction with the FC. It is important to highlight that they only supply the energy for short periods, which is necessary to allow the FC to achieve steady state. One can also conclude that they are also very attractive for battery storage systems, since the batteries provide energy only during longer interruptions improving, therefore, their working life. In this context, this paper presents a single-phase HPF frontend converter suitable for an online UPS system using a proton exchange membrane fuel cell (PEMFC) as an energy storage system. Different to ordinary FC UPS as shown in Fig. 1(a)

A self-resonant zerocurrent and zero-voltage-switching pulse width modulated cell (SR-ZCS-ZVS-PWM) is used, therefore, besides the soft commutation of switches S1 (main) and S2 (auxiliary), the charge circuit for the supercapacitor bank is also ensured. A supercapacitors bank is able to operate without hindrance at 60% to 100% of rated voltage. Normally, a dedicated control is needed to achieve this condition, such as the smoothing control method presented or the sliding mode control shown in this context, one must emphasize that in the proposed system there is no need for a dedicated energy storage control on the supercapacitors. The power diode D1 , which connects the supercapacitors bank with the boost inductor LB , provides the path for the transference of the stored energy to the output capacitor when the main switch S1 is OFF and diode D0 is forward biased, therefore, controlling the voltage level across the supercapacitors terminals in a natural flowing manner. The amount of energy processed by the SR-ZCS-ZVS-PWM commutation cell is transferred to the supercapacitors bank every switching cycle. In steady state, the supercapacitor supplies energy to the load only when the input ac voltage is lower than its terminal voltage and, hence, diode D1 is forward biased. Under a power failure condition on the ac grid, the switch S3 is turned ON and the supercapacitors provide the necessary condition for the startup of the PEMFC.

A boost converter (step-up converter) is a DC-to-DC power converter with an output voltage greater than its input voltage. It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element, a capacitor, inductor, or the two in combination. Filters made of capacitors (sometimes in combination with inductors) are normally added to the output of the converter to reduce output voltage ripple.

The elimination of dedicated dc–dc converters, as well as batteries and associated charging systems, results in significant size and cost reduction and in improving the reliability and working life of the system. The dynamic performance of the proposed FC UPS system was improved using a decoupling supercapacitors bank which is continuously connected to the system assuring conditions for the prevention of critical operation situations during the startup of the FC along with zero switching delay of the ac power to the PEMFC. The DSP-based control technique is based on the average current control method for sinusoidal input current imposition and dc-link voltage control. Theoretical analyses were presented and corroborated with experimental results. It was shown that high input power factor, low harmonic distortion of current, and improved dc-link voltage regulation for the connection of other electronics loads can be achieved. Special attention was given to the dynamic performance analyses of the proposed solution under conditions of ac power supply interruptions showing that the FC is activated assuring the continuous energy supply.
