“…In this paper, the BI-MOV protecting device is tested in combination with a real PWM DC-DC converter, which results to be a non-linear and time-varying EUT. This work completes the analysis started in [21] proving the method reliability and effectiveness for an operative case, useful from the practical point of view. A typical PWM DC-DC Buck-Boost (BUBO) power converter is selected for the evaluation of the effectiveness and the reliability of this technique in the avionic environment, because it provides an output voltage, which cane both higher and lower than the input voltage.…”

“…The use of series inductor in the place of a series resistor with the MOV is a better solution to the problem. The BI has been combined with a MOV to protect, in general, an Equipment Under Test in DC power lines in [21]. The BI has negligible insertion loss and has been already used as an effective solution to dampen the transients in power transmission lines.…”

“…The thickness b of the lamination sheet is discretized in mmax number of points along the direction y to solve (23). More details about the modelling of the ferromagnetic core inductor using the diffusion equation can be found in [21]. The paper here presents the implementation of that formulation for the proposed DC-DC power converter.…”

“…In this paper, the effects of indirect lightning pulses on a PWM DC-DC power converter are modeled, and a suitable protection system consisting of the combination of a series Blocking Inductor (BI) and a Metal Oxide Varistor (MOV) is designed and tested. This configuration has been previously presented and studied in [21] in a standalone configuration. It can protect sensible devices that require low clamping voltage during severe lightning phenomena.…”

“…Effectiveness of the protection system is strictly dependent on the equivalent impedance of the Equipment Under Test (EUT). The analysis presented in [21] with the proposed protection device was not complete rather partial, because the EUT was a simple linear and time-invariant dipole. In this paper, the BI-MOV protecting device is tested in combination with a real PWM DC-DC converter, which results to be a non-linear and time-varying EUT.…”

Purpose The purpose of this paper is to discuss the importance of testing avionics systems during the development phase according to standard procedures outlined in documents such as RTCA DO-160G. Specifically, it focuses on the necessity of correctly designing electronic devices to successfully pass tests for environmental conditions. Design/methodology/approach During the development of the flight reconfiguration system (FRS) within the Clean Sky 2/Clean Aviation cost optimized avionics System (COAST) project, this paper applied solutions for input power protection in electronic design. The methods discussed are aimed at protecting circuits from input power disturbances following Sections 16 and 17 of DO-160G. The approach includes both computer simulations and laboratory testing to analyze the effectiveness of the applied methods.
