Abstract:
This note reports on a novel power supply design for gliding arc discharge with applying controlled phase-chopping on the input voltage waveform, aiming at simultaneously satisfying the decomposition efficacy and energy efficiency for volatile organic compound decomposition. With a proper control on the phase-chopping fraction, the energy efficiency can be obviously enhanced, while the decomposition efficacy is almost maintained, possibly due to the compensation from long-life radical induced decomposition during discharge intervals.

Van de Graaff uses both smooth and pointed surfaces, conductors, and insulators to generate large static charges and, hence, large voltages. A substantial excess charge can be deposited on the sphere because it moves...
Charging Conductors By Induction
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...
