| Abstract: | Based on dsPIC30F6014 digital signal controller （DSC）, to achieve a single-phase Boost PFC using all-digit al control. Digital switching mode power supply technology can achieve the realization of advanced control strategy, simplify the structure of the system, reduce the size and improve system performance. This paper provides a single-phase Boost PFC converter complete digital control solutions. At first, given the parameters of the PFC control system options; and then discussed the Boost PFC solutions based on dsPIC, including the main circuit parameters, the system structure and software design. Finally, the 1 000 W power levels and the simulation results, to verify the fine performance of digital control PFC. |
