“…All this increases the chance that in space-confined designs the flying capacitance has to be chosen close to its critical value, thus increasing the probability to violate Equation (10). Taking into account the ageing effects of MLCC as well [24][25][26], the aforesaid becomes even more likely. Furthermore, the situation becomes even worse if diodes D 11 and D 22 are replaced with a synchronous MOSFET, in order to boost the efficiency even further.…”

The interleaved buck converter with an extended duty cycle is analyzed in terms of unexplored parasitic switching states that diminish the switch utilization and its safety due to high-magnitude charging and discharging currents. The analysis explains the origin of the states and their effects and demonstrates their correlation with the existing voltage ripple on flying capacitors. The article further demonstrates that the voltage ripple can no longer be arbitrarily chosen as parasitic states emerge whenever the ripple exceeds an identified critical value being equal to the twofold voltage drop on the diode. A simple design criterion for flying capacitance is proposed. For a limited set of battery-powered DC-DC converters, a solution permitting the use of smaller capacitance by adding an extra switch is proposed. The derived findings are verified using experimental and simulation results.

“…1,2 Palladium, one of the PGMs, has a high melting point, high heat resistance, high corrosion resistance and unique catalytic properties. 3,4 Owing to these properties, palladium is being widely utilized in many industrial fields, most notably as an automobile exhaust catalyst where it is used to convert noxious emissions to harmless products, 5 in electronic devices such as multi-layer ceramic capacitors and hybrid integrated circuits, [6][7][8] as a potential candidate in drugs 9 and asan efficient catalyst in various chemical conversions. [10][11][12] However, the availability of palladium in the earth's crust is scarce and its accelerating consumption is causing stress on natural resources, thus making it precious and quite expensive.…”

In order to improve the detection efficiency and quality of reliability screening for electronic component in military industry such as aerospace and aeronautics, and eliminate the hidden safety hazards caused by manual inspection operation, the ceramic capacitor automatic test technology was applied to the electrical performance testing of reliability screening process. An new original automatic detection system by using auto test technology of automatic loading and unloading, instrument automation control and parallel testing was designed and developed to realized one-key automatic measurement of capacitor four parameters such as capacity accuracy, loss, insulation resistance and dielectric withstand voltage. It solved the test quality problem that test data could not be automatically recorded and avoided the harm caused by high voltage and short circuit in the detection process. Finally, with the practical application and test, the efficiency and quality of detection process was improved.
