This paper proposes a utility supply driven single stage PFC based LED driver using Cúk converter. For low DC voltage output requirement of LED driver, Cúk converter is a convenient choice due to its topological suitability for PFC application and stepping the voltage down at a desired level unlike the Boost Converter. A hysteresis current control scheme is adopted to operate the converter in Continuous...
An improved algorithm for MTPA (Maximum Torque Per Ampere) and Field Weakening operation which is suitable for implementation with Field Oriented Control, has been proposed for the Synchronous Reluctance motor (SynRel) for high dynamic performance. The proposed method overcomes the problem of excessive current flow into the machine while generating the d-axis and q-axis current commands independently...
