DSP-Based T-Type Three-Phase PFC Charging Pile Solution

DSP-Based T-Type Three-Phase PFC Charging Pile Solution

Abstract With the popularity of new energy vehicles, efficient and stable charging piles have become important supporting facilities. This paper proposes a DSP-based T-type three-phase Power Factor Correction (PFC) charging pile solution, supporting a DC output of 500-1000V, with a maximum current of 60A and an output power of 30KW. By adopting the T-type three-phase … Read more

DIY LLC Current Mode Control Scheme with NCP1399

ON Semiconductor released the LLC current mode controller NCP1399 in the third quarter of 2016, addressing the shortcomings of the LLC controller’s purely voltage-frequency mode. In official comparisons, it performs excellently compared to NXP’s TEA1716 (which I have used in ARM projects). ● Power Characteristics① Universal AC input range. ② Active PFC, PF>0.97. ③ Efficiency … Read more
