The Net Zero Mass Loss Phenomenon on Opening Switching Contacts with AC Loading - Components and Packaging Technologies, IEEE Transactions on [see also Components, Packaging and Ma

Studies are conducted on silver metal oxide contacts on a purposed built apparatus to investigate the extent of contact erosion under opening (break) operations. The contacts are opened between 0.1 and 0.8 ms 1 at particular point-on-wave, tPOW, of the ac waveform. Current loading of up to 30 A rms, Irms, is investigated. Contact material deposition, as well as mass loss, is observed and is fou...

A Zero Current Switching AC-AC Resonant Converter

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. Induction heating is a process which is used to bond, harden or soften metals or other conductive materials. For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency and control. The induction he...

A Zero Current Switching Ac-Ac Resonant Converter for Three Phase Induction Heating

This paper proposes the concept of three phase ac to ac resonant converter for Induction heater. As compared with basic converters, ac to ac resonant converter has advantages of less components count, low cost, high reliability and better efficiency. A closed loop control structure is proposed in this paper for controlling three phase resonant converter. Finally, this proposed system is experim...

Low Dimensional Modeling of Zero-Net Mass-Flux Actuators

The flow field generated by a zero-net mass-flux (ZNMF) actuator is investigated via both numerical simulations and experiments to augment the current understanding of the flow physics of the orifice. The results aid in improving the accuracy of low dimensional lumped element ZNMF models suitable for design. Dimensional analysis yields a number of key parameters that govern the characteristics ...

On Matter with Zero Rest Mass

Further imagine two events. Event e1 is associated with the transfer of energy E and momentum p1 from particle 1. Event e2 is likewise associated with particle 2's transfer of energy and momentum from particle 1. As a consequence of the situation as shown in figure 1, these events must occur at the same time and place. But is there another reference frame S in which these events do not occur at...
