Switch Mode Power Converter Section

SMPCS is involved in design and development of power converters for electromagnets of Indus-1 and Indus-2 synchrotron radiation source, Infra-red Free Electron Laser (IRFEL) and other applications including laser diode drivers, induction heating power converters etc. SMPCL is also involved in design and development of power converters for Facility for Antiproton and Ion Research (FAIR), Germany.

Working mainly with the switch-mode, hard-switching as well as soft-switching power converter topologies, the team members have gained expertise in the analysis and design of various power converters, feedback control design, high-frequency magnetic, electromagnetic compatibility issues etc. Highly stable output-current-controlled power converters for electromagnet with stability up to 50 ppm have been developed.

In addition to ongoing projects, the laboratory is presently working on the development of power converters with output current controlled stability of 10 ppm, development of FPGA based digital controller, modeling and analysis of reliability of power converters. A new family of resonant converters, called the resonant immittance converters, has been identified that has myriad of applications and fetching the attention of researchers worldwide. Many applications such as a crow-bar-less high-voltage power converter, ultra-capacitor charger, induction heating power converters have been developed using the resonant immittance converters.
