STEVAL-IPFC12V1

設(shè)計簡介

The STEVAL-IPFC12V1 2 kW interleaved PFC converter kit provides very high power factor supply power with very low harmonic distortion and features advanced dynamic performance and condition monitoring, including analog 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 (analog/digital) average current mode control in CCM at fixed frequency.
You can use the eDesignSuite software available on the ST website to configure the STNRGPF12 according to your design requirements for each interleaved PFC.
