Question

Which answer from the following list is a major advantage of switched mode power supplies over series regulated supplies? *
Switched mode supplies work digitally, so are more efficient than series regulators.Gate
Switched mode supplies create smaller amplitude ripple waveforms than series regulators.
Switched mode supplies dissipate less power in the control element than series regulators.
Switched mode supplies provide better regulation at low power than series regulators.​

Answer 1

Answer:

${\tt{\pink{\underline{\underline{\huge{answer:}}}}}}$

☞Switched mode supplies create smaller amplitude ripple waveforms than series regulators

Answer 2

The correct answer is option (c) Switched mode supplies dissipate less power in the control element than series regulators.

Explanation:

• The major advantage of switched mode power supplies over series regulated supplies is that the Switched mode supplies dissipate less power in the control element than series regulators.
• On of the disadvantage of switched mode power supplies compared with series regulated supplies is that it is more difficult to prevent high frequency electrical interference in switched mode supplies.
• Hence, the correct answer is Switched mode supplies dissipate less power in the control element than series regulators.
