A general purpose aerosol conditioning device called the Universal Aerosol Conditioner (UAC) has been designed and tested. The may be used to condition an in multiple ways: dilute entire (gas- particle-phase), only a gas-phase component of without diluting particle concentration, denude by removing semi-volatile material from phase, humidify or dehumidify aerosol. UAC accomplishes these process...

Thermodynamics is a funny subject. The first time you go through it, you dont understand it at all. The second time you go through it, you think you understand it, except for one or two small points. The third time you go through it, you know you don't understand it, but by that time you are so used to it, it doesn't bother you any more. Global climate results from a thermodynamic interaction b...

This paper deals with a three-phase unified power quality conditioner (UPQC), with a combination of shunt active power filter and series active power filter is used to eliminate supply current harmonics, compensate reactive power, voltage sag and voltage swell compensation on distribution network. The performance of the active power filter mainly depends on control strategy used to generate ref...

A Unified Power Quality Conditioner (UPQC) is designed using a Neutral Point Clamped (NPC) multilevel inverter to improve the power quality. When designed for high/medium voltage and power applications, the voltage stress across the switches and harmonic content in the output voltage are increased. A 3-phase 4-wire NPC inverter system is developed as Power Quality Conditioner using an effectual...
