The terms DC–DC converters and choppers are one and same. In the texts usually these terms are interchanged . The Choppers can be operated in either a continuous or discontinuous current conduction mode. They can be built with and without electrical isolation. Chopper - Definition: A chopper is a static device that
The cyclo converters generally produce output AC voltage at a lower output frequency. That is output frequency of the AC output is less than input AC supply frequency. Applications of cyclo converters are traction vehicles and gearless rotary kilns. 3. CHOPPERS or DC TO DC Converters. The choppers are power circuits

achieved using switched-mode, or chopper, circuits whose elements dissipate negligible power. Pulse-width modu- lation (PWM) allows control and regulation of the total output voltage. This approach is also employed in ap- plications involving alternating current, including high- efficiency dc–ac power converters (inverters

Power electronics (PE) experienced tremendous growth after the introduction of the first solid-state power switch, the silicon controlled rectifier conceived during the 1920s and 1940s (like the cycloconverter, the chopper, and.
