Option 3 : 2 and 3 only

Switched Mode Power Supply:

It is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power), to DC loads, such as a personal computer, while converting voltage and current characteristics. It is suitable for low power circuits.

It uses a dc to dc switching converter switched at high frequency. The following devices can be used as switching mode DC power supplies:

Flyback converter
Push-pull converter
Half-bridge converter
Full-bridge converter

Advantages:

Lower Weight
Smaller Size
Higher Efficiency
Lower power dissipation
Wide AC input voltage range
