“…Figure 3 presents in detail the aforementioned converter topology; the two converters are connected in series to perform the virtual electrical power consumption at the circuitry input-i.e., the Buck converter's side-and the electrical power recovery at the circuitry output-i.e., the Boost converter's side-having negligible actual power consumption. The virtual power consumption concept is imposed via the Pulse Width Modulation (PWM) control technique that has been selected to drive both Buck and Boost converters; more specifically, in the Buck converter case, the Peak Current Control switching strategy is selected [15][16][17], while in the Boost converter case Average Power Control technique is used [18][19][20]. This way, the appropriate switching pulses for each control strategy are applied to switches S Buck and S Boost .…”

In this work, the development of an energy recovery control unit to be incorporated in the light-emitting diodes (LEDs) lighting systems of heavy-duty vehicles is presented. This innovative industrial product adopts modern power electronics technology to improve existing trucks’ LED lighting system by eliminating the so far inevitable power consumption by the conventional central control unit of the majority of these vehicles, which is obligatory for the uninterruptable operation of their lighting system. The main idea of this innovative product is its capability to virtually increase the lighting system power consumption without actually consuming this amount of energy, thus facilitating the central control unit requirements regarding these vehicles in an energy-conscious way. Under this light, a mature power converter’s topology is employed to draw the proper amounts of power from the vehicle’s batteries supply, to the level that the central control unit recognizes, and return this energy back to the batteries. The tests results of the developed industrial product highlight the energy saving potential of the proposed energy recovery scheme, while the Life Cycle Cost Analysis (LCCA) results confirm its techno-economical and environmental profit for the truck applications under study.

“…In both cases, synchronous operation can be supported, because of the half-bridge configuration of the topology. If synchronous operation is not desired, then the antiparallel diode of the inactive switch operates as a freewheeling diode [22]. In addition, the converter may operate either in Continuous Conduction Mode (CCM), or in Discontinuous Conduction Mode (DCM), depending on the inductor current.…”

“…The CCM operation is designed for a wide range of operation, by properly selecting the inductance value (L) and the switching frequency (f s ) of the converter. The necessary internal current control loop is based on the Peak Current Control (PCC) method and it is digitally implemented with the aid of a microcontroller unit [22,[24][25][26].…”

“…On the other hand, the drawback of subharmonic oscillations is common in both step-up and step-down DC/DC converters operating in CCM under current-mode control. However, these oscillations are successfully damped with the addition of a compensation ramp (which is actually a saw-tooth waveform with negative slope), with properly calculated slope, to the control signal [22]. The procedure of the slope calculation for a properly designed compensation ramp is presented in detail in Appendix A.…”

The objective of this paper is to present a power conversion system, based on a bidirectional DC/DC converter, along with a supercapacitor bank, that mitigates the voltage transients that occur on the DC distribution network of More/All Electric Aircrafts. These transients, such as voltage sags and swells appear on the DC buses of on-board microgrids, mainly due to load variations and are classified according to the aircrafts electric power system standards. First, we shortly describe an aircraft distribution network, that is applicable to the most common actual aircraft architectures, then we present the proposed system, along with the bidirectional DC/DC converter design, the control technique and the supercapacitor bank sizing. Finally, we present simulation and experimental results that support the effectiveness of the proposed system to effectively compensate voltage transients, supporting the DC buses in dynamic conditions. Concluding, the proposed system provides high power quality and compliance with the respective power quality standards for aircraft microgrids.
