14. ANALISE E PROJETO DO CONVERSOR BUCK INTERCALADO PARA ALIMENTAÇÃO DE LÂMPADAS DE DESCARGA EM ALTA PRESSÃO DE ALTA POTÊNCIA / INTERLEAVED BUCK CONVERTER ANALYSIS FOR HIGH POWER HIGH INTENSITY DISCHARGE LAMPS SUPPLYING
This work presents a detailed analysis about the interleaved buck converter applied to electronic ballasts to supply high power HID lamps, assuming the input voltage as a PFC stage output. As the output capacitor has a maximum value to be applied in parallel with the lamp, parallel operated converters are a suitable choice because the output current ripple c

17. Control of strain in a flexible beam using Ni-Ti-Cu shape memory alloy wire actuators
In this paper the development of an experimental test bench to analyze and control the strain of a flexible aluminum beam subjected to external disturbances is described. In the proposed platform, strain-gauges are used to measure the strain of the beam in a single cantilever mode while Ni-Ti-Cu Shape Memory Alloy (SMA) wires are used as force actuators. Dat
