Experimental analysis on the variable polarity plasma arc pressure
variable polarity plasma arc arc pressure orthogonal experiment
2011/8/5
Arc pressure is one of the key factors for variable polarity plasma arc(VPPA) and welding pool formation. In this paper, VPPA pressure was measured by pressure transducer and U-tube barometer methods....

FDNR Positive Polarity Current Conveyors
2010/12/7
A generalized circuit based on five positive polarity second-generation current conveyors is introduced. The circuit simulates a floating inductance, capacitor floatation circuit and floating fdnr. Al...
Economical and Accurate Digitally Programmable Dual-Polarity Gain Amplifier
Dual-Polarity Gain Amplifier switches
2010/12/14
A digitally programmable, dual-polarity gain amplifier is proposed. It uses total resistance less than those presented earlier. The effect of on-resistance of switches can be fully compensated.
