Designed a digital control based single-phase AC-DC converter with power factor correction and a stable voltage (36V, 2A ) output, of which the output power is controlled by a DSP microcontroller in 4 days.
Used a Boost DC-DC converter for the PFC and after DC converter stage in the Active Power Factor Correction part.
Measured the power factor of the input AC bus and changed the power factor by human-machine interface, the output voltage can realize certain load regulation and voltage regulation requirement
