What is pure DC current?

Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.

What is the difference between pulsed DC and AC current?

In a traditional AC current waveform, the voltage is variable as it rises up and down along the wave. Pulsed DC shares this characteristic with AC current but, unlike AC current, the polarity of the current does not change. Like traditional DC current, pulsed DC maintains a single positive or negative polarity.

What is meant by pulsed DC?

Pulsed DC. Pulsed DC ( PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular (“flat-topped”), rather than sinusoidal, pulses. Pulsed DC is commonly produced from AC ( alternating current)…

What is the difference between PDC and DC current?

The plasma generated using PDC is more reliable than that created by regular DC current because it cannot be poisoned by the buildup of argon gases. As a result, PDC magnetron sputtering is considered to be superior to regular DC current in the production of thin film materials.

What is the difference between alternating current and pulsating current?

Pulsating direct current has an average value equal to a constant (DC) along with a time-dependent pulsating component added to it, while the average value of alternating current is zero in steady state (or a constant if it has a DC offset, value of which will then be equal to that offset).
