When such flashovers occur, they may short-circuit the alternating current power system, and the resulting power arc may start a fire.
For example, a set may be designed to convert commercially available alternating current to direct current, as in some welding applications; or it may provide high-frequency alternating current power for induction heating.
A novel meander-line structure implemented with bimorph piezoelectric actuators driven by two sets of alternating current power with phase difference is developed in this article.
One of the challenges was to minimize AC, or alternating current, power loss to make AC motors and generators efficient, this at a time when DC, or direct current, prevailed.
Many hydropower turbines rotate at a relatively low speed and they require generators with multiple poles in order to be able to produce alternating current power at the grid frequency.
The lowest contact angle of 9° with the higher photoresist ER of 210 nm/min was obtained with (4 slm He+40 sccm O2)/Ar (20 sccm) at 400 W of alternating current power.
A smaller 671-kW head-end power (HEP) engine is used to generate alternating current power for "hotel services" in the passenger cars, such as lighting, heating, and cooling.
This dual approach for contrast enhancement also succeeded in overcoming fluctuations in illumination caused by the alternating current power source.
The alternating current power supply is a commercial transformer capable of generating continuous and tunable output voltages and frequencies.
A double-sided surface light source based on field emission (FE) using an alternating current power source is demonstrated.
Today, electric cars almost always use the existing alternating current power grid for charging, which means that the energy must first be converted from A.C. back into the D.C. format car batteries use to store energy.
