Answer: A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission).
Answer: 1.4 DC TO DC CONVERTERS. Dc to dc converters, called choppers, are supplied from a dc voltage source, typically a diode rectifier and a dc link, as shown in Fig. 1.37. The dc link consists of a large capacitor connectedacross the input terminals of the chopper and, often but not necessarily, a series inductance.
Answer: Safety requirements are a common reason to use an isolated power converter. For converters powered from high and potentially hazardous voltages (such as ac-dc converters powered from ac mains) isolation separates the output from dangerous voltages on the input.
