Question E7D10
From subelement E7 - E7D
E7D10
Answer: CWhy is a switching type power supply less expensive and lighter than an equivalent linear power supply?
AThe inverter design does not require an output filter circuit
BThe control circuitry uses less current, therefore smaller heat sinks are required
CThe high frequency inverter design uses much smaller transformers and filter components for an equivalent power output
DIt recovers power from the unused portion of the AC cycle, thus using fewer components
