Question

question 4 of 7
select the correct name for this ac wave shape:
ac soft squarewave
advanced squarewave ac
sine wave ac
advanced sine wave ac
advanced triangular wave shape ac
submit

Explanation:

Analyze the waveform geometry

Using the AC Waveforms knowledge point

• The graph plots Amperage on the vertical axis against Time on the horizontal axis for one complete AC cycle.
• The transition between the positive (+) and negative (-) half-cycles is extremely rapid and vertical, forming sharp, square corners.
• The top and bottom of the wave are flat, horizontal lines.
• This geometric profile represents a standard squarewave.

Identify the specific squarewave type

Using the AC Waveforms knowledge point

• Standard squarewaves with instantaneous transitions are referred to as advanced squarewaves in modern inverter power sources.
• Soft squarewaves feature slightly rounded corners to provide a smoother arc.
• Since this wave has perfectly sharp, square corners and instantaneous zero-crossing transitions, it is classified as an advanced squarewave.

Answer:

• AC Soft squarewave
• Advanced squarewave AC (Correct answer)
• Sine wave AC
• Advanced sine wave AC
• Advanced Triangular wave shape AC
