Abstract
A single DSP controlled two phase interleaved PFC converter is presented together with Its digital control design and implementation. A simple, low cost method of sensing the switch current and implementing the current share control is illustrated. Details of the design are presented to show the simplification of the control Implementation achieved through the use of a DSP. Finally, experimental results are provided to validate the performance of the digital implementation.
