“…6. Its voltage, power control loops and protection specifications are listed in Table I of [39], [40], where V F Cmin and V F Cmax and P omax have been changed into 26.0 V, 42.0 V and 1.2 kW, respectively, due to the FC emulator was replaced by a real PEMFC. We have chosen a 600 mF commercial electrolytic capacitor with an Equivalent Series Resistance (ESR) of 1 mΩ.…”

“…This master control sends the current references to the analog current loops of each converter to regulate the different voltages of the system. The master control parameters are listed in Table II of [39], [40] and it has been implemented on a Texas Instruments TMS320F28335 DSC. Fig.…”

“…Its advantageous features include high power conversion efficiency, wide bandwidth, the possibility of controlling either the input and output voltages or currents [37] and achieving fast and smooth transitions when changing the control objective from controlling the input current to control the output current and vice-versa [38]. This module has been used previously in a simple FC series hybrid topology [39]. The series-parallel hybrid topology challenges gave rise to the non-inverting buckboost converter and it is now presented for the first time in the topology for which it was designed.…”

In this work, a serial-parallel hybrid (SPH) power system formed by a Fuel Cell (FC), an Auxiliary Storage Device (ASD) and the current-controlled dc-dc converters responsible for the power management are realized by using the Digital Signal Controller (DSC) TMS32F28335. The main energy management goal is to transfer energy from the sources (FC or ASD) to the load while ensuring dc bus voltage regulation and high power conversion efficiency. In addition, a safe and reliable operation of the system has to be achieved. The selected converter and its controller features are: non-inverting voltage step up and step down, high efficiency, input and output currents regulation an low ripple values, and the ability to change from input to output current regulation loop, suddenly and smoothly, and vice versa. All these features allow it to be positioned in different FC system localizations and simplifies the design of the master control. Simulation and experimental results have been validated on a 48-V, 1200-W dc bus.
