EVAL KIT , INTERLEAVED CCM PFC DIG CTRL

2KW two-channel interleaved PFC converted kit based on the STNRGPF12 digital controller with digital inrush current control. This converter kit provides very high power factor supply power with very low harmonic distortion and features advanced dynamic performance and condition monitoring, including analogue cycle-by-cycle current regulation. Digital functionality is based on the STNRGPF12 digital PFC controller which features digital inrush current control and can drive up to two interleaved PFC channels with mixed signal (analogue/digital) average current mode control in CCM at fixed frequency. Users can use the eDesignSuite software available on the ST website to configure the STNRGPF12 according to their design requirements for each interleaved PFC. The 2KW interleaved PFC evaluation kit features STEVAL-IPFC12P1 power board, STEVAL-IPFC12C1 control board, STEVAL-IPFC01A1 adapter board.
