Why is a switching type power supply less expensive and lighter than an equivalent linear power supply?

• A. It recovers power from the unused portion of the AC cycle, thus using fewer components
• B. The control circuitry uses less current, therefore smaller heat sinks are required
• C. The inverter design does not require an output filter circuit
• D. The high frequency inverter design uses much smaller transformers and filter components for an equivalent power output
