Cogeneration for small users: case studies for Brazilian tertiary sector
(1995-12-01)
In this paper we present technical and economic studies of cogeneration systems utilizing combustion engines and gas turbines, applied in two establishments of the tertiary sector, regarding Brazilian conditions (according ...
Microstructure evolution during warm deformation of low carbon steel with dispersed cementite
(2007-12-01)
The microstructure evolution and mechanical behavior during large strain of a 0.16%C-Mn steel has been investigated by warm torsion tests. These experiments were carried out at 685°C at equivalent strain rate of 0.1 s . ...
Single-phase high power-factor boost ZCS pre-regulator operating in critical conduction mode
(IEEE, 2003-01-01)
This paper presents a new single-phase interleaved high power factor boost pre-regulator operating in critical conduction mode, where the switches and boost diode performing zero-current commutations during its turn-off, ...
