Which of the following is NOT a topology of an SMPS?

Explanation:

The correct answer is option 2) Reverse converter.

Switched-Mode Power Supplies (SMPS) are a category of power supply circuits used to convert one form of electrical energy into another, typically to efficiently convert and regulate voltage levels. They are commonly used in a wide range of electronic devices, including computers, smartphones, and various types of equipment.

1. Forward Converter:

A forward converter is a type of SMPS that converts input voltage to output voltage in a forward manner. It steps down or steps up the voltage, depending on the application, and is widely used in various electronic devices.

2. Reverse Converter:

The term "reverse converter" is not a recognized or commonly used term in the context of SMPS topologies. It is not a standard or established topology for power conversion. SMPS topologies are typically categorized as forward converters, flyback converters, boost converters, buck converters, and other well-defined configurations.

3. AC to DC Converter:

This is a broad category that includes various SMPS topologies like rectifiers and power factor correction circuits that convert alternating current (AC) voltage into direct current (DC) voltage.

4. DC to DC Converter:

DC to DC converters are SMPS circuits that convert one DC voltage level to another, either stepping up (boost converter) or stepping down (buck converter) the voltage.

In summary, the term "reverse converter" does not correspond to a recognized SMPS topology. SMPS topologies involve forward conversion, not reverse conversion, when it comes to voltage conversion processes.
