DC-DC Converters

Question 1

What do DC-DC converters do?

Answer 1

DC-DC converters change the voltage level of direct current (DC) from one value to another.

Question 2

How do DC-DC converters work?

Answer 2

They use switching techniques, inductors, capacitors, and diodes to step-up, step down, or invert DC voltage.

Question 3

What are the main types of DC-DC converters

Answer 3

Buck (step-down), boost (step-up), buck-boost, and flyback converters.

Question 4

What is a buck converter?

Answer 4

A DC-DC converter that steps down the input voltage to a lower output voltage.

Question 5

What is a boost converter?

Answer 5

A DC-DC converter that steps up the input voltage to a higher output voltage.

Question 6

What is a buck-boost converter?

Answer 6

A converter that can either increase or decrease the input voltage, depending on the circuit configuration.

Question 7

What is a flyback converter?

Answer 7

A converter that uses a transformer to provide isolation and voltage conversion, often in high-voltage applications.

Question 8

What is a SEPIC (Single-Ended Primary Inductor Converter)?

Answer 8

A DC-DC converter that can step up or step down voltage with continuous input and output currents.

Question 9

What is the efficiency of a DC-DC converter?

Answer 9

The ratio of output power to input power, typically expressed as a percentage.

Question 10

What is the switching frequency of a DC-DC converter?
